But when I open the back the roll is tightly wound with no leader hanging out.
After it happened on four or five rolls, I opened the back enough to peek in, saw the backing paper sticking to the roller, then when I opened the back fully, no tab hanging out. Wipe the inside of the Holga with some isopropyl alcohol and see if you get any gunk. The other thing is the new clips are holding the back tighter and may be keeping it from fully rolling until the pressure is off of the roll. If it was the camera, there would be leaks at other places. It couldn’t hurt to try.
What do you mean by 'roller'? There is no roller in the Holga - just the film spool and the film take up spool. And it has never happened before on any of them - just this one time.
I will wipe the inside as suggested - can't hurt!

The Horseman back has a tension roller, which I wouldn’t expect the Holga to have. I was just curious if there was a burr or a sticky spot on the back that the backing paper is catching on.
It’s had enough rolls through it that if it was the camera it would have shown up earlier.
Somehow it looks like light is hitting the end of the roll as it’s coming out of the camera.

Ok, one for the peanut gallery. Dr G took these w her 'Olga 120 (Baby Blue) and these two shots - the last on the roll, have this very specific light leak with backing paper markings.
Is it possible she forgot to tape over the red window for those shots, or maybe she left it untaped while she wound the film the rest of the way onto the spool in bright sunlight? I sometimes see backing-paper light leaks in photos shot with expired film where the backing paper is old and has lost some of its opacity, but it's also possible that the backing paper itself had some irregularity or ink transfer onto the film toward the end of the roll.
I would think the most likely way to get a light leak that shows backing paper would be through the red window. My guess is that she had the red window taped over for the shot, but then she removed the tape to watch as she started to wind on the film the rest of the way onto the spool; based on the photo it was sunny out, and she probably had the red window in the sun so she could watch the film wind on. If the backing paper wasn't totally opaque that could explain it.
However, I'm mystified by the number 13 in one of those frames: 1) if the image of the backing paper was being projected onto the film by light coming in through the red window, shouldn't that number appear backwards on the final image? and 2) if she had the red window set up properly it should only show the frame counters for 6x6, which only go up to 12. Number 13 should only be visible if the red window mask was set up to show 6x4.5 frames. Furthermore, I don't think number 13 would show up so close to the end of the film since the 6x4.5 numbers go up to 16; it lines up approximately with frame 10 on 6x6. So maybe my theory isn't so great after all. Doing a little research online suggests that the ink from some backing paper can transfer to the emulsion, especially if it has ever been exposed to heat or high humidity, but that wouldn't explain the light leak. Maybe your idea that the lab caused this is on the right track.
Thanks! The lighting was perfect this particular morning and NLP really nailed the conversion. I couldn't get the colors right with my Silverfast version of the scan.

The backing window is left uncovered on all the Holgas we use - as intended as they are used to show frame #. And this has never happened before, and only was on the last two frames!
Which is why I think it is a lab issue.
