ISTA+ Expert mode

Hello to all!

Today I tried to update i-level of my BMW F10 with ISTA+ 4.10.20. It gave me a list of units to update but I wanted to skip updating of some units as I have there installed modified SW from different versions (EGS, KOMBI, HKL...)
In ISTA/P it was possible but here in ISTA+ I didn´t find any way to uncheck already chosen units by the program. They are greyed out. I think I don´t have expertmode of ISTA+ enabled as in registry when I set expertmode to false nothing changed in programming options of ISTA+.
Doesn´t anybody have any clue how to edit ISTA+ update plan? Or force expertmode in ISTA+?
My registry address is:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\BMWgroup\ISPI\Rheingold
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\WOW6432Node\BMWGroup\ISPI\Rheingold
BMW.Rheingold.Programming.Enabled - True
BMW.Rheingold.Programming.ExpertMode - True


Thanks!
