Unable to change or edit speaker names in transcript

I am using Premiere Pro 22.6.2 (Build 2). I have Premiere transcribe a sequence and check the box for it to recognize different speakers. All good.

But when I click on the speaker in the transcription window, it does not allow me to change to another speaker. And when I choose to edit the speaker name, the same does not save.

I used to be able to do this and it's a great feature. Has anyone else had this problem? Is there a fix?
