Fabfilter pro q3-filter screen disappears in realtime

Win 10-Audirvana 3.5.46-VST3 Fabfilter pro 3
With “Realtime Conrol”, each time I change a preset the filter window moves up the screen. At first, the change filter field at the top disappeared (I had to stop & enter configure to change), now the filter screen has completely dissappeared! Does anyone know how to get it back? Thank, John

This seems to be a Audirvana problem not a Fabfilter one…The same thing happens with Voxengo GlissEQ. My workaround is to move "Fabfilter Pro Q-3.VST3 out of C:\Program Files\Common Files\VST3. Then confirm in AV that there are no plugins. Then move the plugin back. Start AV again, and the EQ window will be back.
Sorry for the confusion (I’m a newbie).

One final post. Right click on 2nd window on Task Bar… Move…Down Arrow…Done!
