Hello,
You have protected all your fields which is causing this issue.
Unprotect the text, extra, pixorize, and sketchy fields.
Then do the following:
Please try resetting your local changes. To do this:
Go to browse in your Anki → at the top click on ankihub addon tab → press reset all local changes
This will restore everything to what AnkiHub has unless you have specifically protected those fields
