Selection menu

I don’t know how to do this anymore. In every tab with a selection menu, for example, Media Player - Music Library - it shows the library. I scroll to choose a song or artist… and I never get to choose because the tab closes. The same thing happens in Grafana, for example. I select ID.etinty, then I want to add a sensor. A list of sensors expands. I can’t choose because before I scroll down to make a selection, the list refreshes and returns to the starting position. Sensors that don’t fit in the window are invisible again, and I have to scroll again, and again I won’t get to choose because the view resets to its initial state. What do I have wrong? What could be causing this?
