@robert.jochim, I have tried to recreate this issue using your custom Tides panel, but I don’t see any problems. I have tried using Bullseye 32 bit on a Pi 3. Remember when the secondary panel selector pops up, you scroll through the options by dragging (using touch) or scrolling (using mouse) on the selection buttons themselves rather than the scroll bar. The scroll bar is there just to indicate that there are hidden options. If you try to drag the scroll bar, then nothing will happen
