The trick is to also add synonym to make it a valid list item

Hi,
I have encountered the same issue as this person. I.e., the 'save' button for adding list key is grayed out.
My entity is newly created, uniquely named, and list key is single english word (purely lowercase alphabetical)

Please let me know if there's anything else I can provide to help troubleshoot.
Thanks,
Shawn

2025-07-06T13:09:44.4433333+00:00 Type key, press tab and add synonym/s, you can see the Save button gets enabled. Note the synonym doesn't appear in text box, but accepts input. (refer attached)
