Single 'blink' when turning on LiteFlux LF2XT

Wonder if anyone familiar with the LF2XT can shed some light on this.

Every time I turn on the light it does a single flash before coming on to the 1st FUI programmed mode. In this case it's set to lowest output so when doing a single press on it will blink once (at the light output level 1 is set to) then stay on. I can change the brightness level to anything from lowest to 100% and it still happens.

This happened once before and somehow I hit a possible button press combination that stopped it happening so I'm thinking it's a programming error rather than hardware.

It's has momentary enabled.
Click 4 times to disable.

That did the trick, thanks! Missed it in the flow chart as I wasn't sure what it was doing
