Chord Symbol Popover disappears when using arrow keys

In Cubase 15.0.10 the Chord Symbol Popover disappears when using arrow keys to move from beat to beat. This feature worked perfectly well in 15.0.06. I have tried rebuilding the preference file but that does not solve the problem

I can confirm that there is something strange in the score editor. I’m not able to move the popover for chordsymbols input, neither with arrow keys nor tab (as I do in Dorico); the popover just disappear.

And the manual (pro 15.0.00 , I’m writing in 15.0.10) doesn’t give me any tips to what I’m doing wrong.

The popover appear after selecting Text/chords/clicking the note. I can write a chord symbol, and then move the popover, but it will not let me put in a new chord, and if I press Tab or Arrow the popover disaapear.
