Cubase 9.5.10 - Using Glue tool to join parts - Project window/position jumps?

I’ve got this unusual thing which has started happening in cubase 9.5.10 after I upgraded.

If i merge midi or audio parts using the glue tool the ‘play-head’ jumps around… is this normal? I haven’t had this stressful position jumping before
Here is a video of it on some midi (instrument) parts.

Resetting/deleting my preferences hasnt fixed it.

Thanks :smiley:

Is it duplicate of this, please?

Yes sorry I wasn’t sure if It needed to be in issues forum or general and then couldn’t delete this one.
