New Keywords not appearing in autofill.

I am running version 12.4 of Lightroom. When I add a new Keyword to the Keyword list, I expect it to appear in the autofill list when I move to a different photo. It does not. It shows in the Keyword list if I search, but it does not appear in the Keyword dropdown when I begin nto type. See example below for Smooth Ox Beetle. I had this problem in the past, but an update corrected it. It seems that the old problem has resurfaced.
