On the Transmitter (trigger) or the Universal receiver pressing and holding the Test button for 5 seconds will switch you from standard to speed mode or speed to standard. The LED blinks once every 5 seconds when units are in standard mode, twice every 5 seconds when in Speed mode.
The most common reason for the switching is people "thunder thumb" the transmitter's test button inadvertently switching it's mode from one to the other. If this happens without any user interference there is radio interference, electro magnetic voltage interference or the module is defective. If radio interference (these operate at 2.4Hz range so wireless network could impact them) change the channels to matching ones on both the transmitter and receiver. EMV can be caused by some flashguns and can sometimes impact the receiver. If this is the case, use a longer cord to connect the receiver to the flashgun. If the Skyport module is defective you'll need contact the Elinchrom agents in the country where you purchased the units.
