Jumping in here - do you have any issues using your adapter? I understand it works better on some Profoto heads than others...
The Eli-Profoto adapter (it's made by Eli) has a silver reflector built in - remove it as that's the source of the problem. It's utterly unnecessary/decorative with Profoto heads due to the dome on the latter.
The reflector JUST (and I mean JUST) narrows the opening down enough that some Profoto heads won't zoom properly. Just remove the reflector and away you go. The same 3-4 screws go thru the reflector and hold the various bits of the adapter together. Just remove them, chuck reflector and re-assemble. Oh, some loctite on the machine screw nuts also wouldn't hurt since you're in there. Whole process takes 10 min.
At that juncture, any Profoto head (Acute, Pro, Compact, D1), no issues, full zoom. Have used my adapters that way for years if/when using any Eli softboxes or tin modifiers.
