Logic Pro global chords track problems

I am trying to use the global chords track to enter chords. It is pretty much unusable.

When i first started with it a few weeks ago, it was a bit dodgy but mostly worked. One example of dodgy: i would doubleclick in the global chords track, and could enter a chord name there. Often it would start the new chord area a little to the right of where i clicked, but fine, i could drag it into place.

Now: The plus sign next to 'Chords' to the left there, clicking that plus does absolutely nothing.

In an empty area of the chords track, crtl-click to get the dropdown menu, choosing 'create chord' does nothing.

Doubleclicking in the chords track does nothing, each click works separately highlighting then unhighlighting that area. I cannot edit chords.

If i ctrl-click where there is an existing chord, in the dropdown menu, 'edit chord' is greyed out.

It all seems buggy and unpredictable.

I did look through the manual. What i experience does not reflect what is there.

I looked through all the preferences too. Nothing about chords that i can find.

I will try to post videos here of what happens.
