Project Browser bug

The project browser won’t let me select some track data events to edit them. Sometimes when I click on a midi event under track data, the right pane flashes the notes and controller messages for that event, but when I let go of the mouse button that information disappears and is replaced by track data and automation headers often for a completely different track. Other times it won’t let me select the event at all. The problem seems to happen when the track has both automation and midi controller messages. Not sure if it happens otherwise. I’m running Cubase Pro 10.5.12 under Windows 10.
