Hi Barry,
I can confirm the issue. I tried the column footers and assign on a newly created draft page to check. There is an error on the console:
You could try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
If this is not a plugin, please check for any customization. Try to remove it and then check again.
Let us know how this goes.
