It’s a bit strange…I type keyword then a comma creates a tag, then next ones are added the same by typing comma at the end. Then I save it, that’s where I got the error.
Now I hit enter before clicking on save button, no error.
I collapse the field and reopen the field, the tags disappeared.
I go out of the page, goes back in, still empty tags.
I refresh the page and go back in then the tags are there.
May be I just need to hit enter key before saving and hard refresh to make sure the tags are save correctly. Just that previous version, I never have to hit enter key. Just comma and click save works.
That’s ok, you can close this ticket.
