KOMPLET KONTROL & DUPLICATE INSTRUMENT TRACKS ISSUE

If I create new instrument track and load any VSTi over KK al graphics and controls are on display and everything works as expected.
But if I use duplicate function on KK instrument track my duplicated instrument loses all graphic information on my KK keyboard.
On Cubase 10.5 everything works normaly, I check every preference and midi setup in my C11 to be set as in C10.5 but still no success.
Anybody else has same problem?
I m on W10 but it is not the problem here, only for info to know:)
