I had the same problem, and the waveform was not updating either.
The easiest for me was to make a "bounce to clip(s)" after selecting both.
It keeps everything on the same track and the waveform is displayed correctly.

I had a similar problem after a Windows update.
Tries to disable USB power saving and checks the DPC latency.
Sometimes going back to 128 or 512 buffer settles the clicks temporarily too.
