1Password in dock is corrupted or missing something

Ok gotcha. I can't say for certain. My itch in the back of my mind is perhaps you were using an expired beta which would require a reinstall. If this continues, I'd recommend allowing our technical team to take a look. Especially, so if this is only happening with 1Password.

Also, if you're using an older version of macOS and have not restarted you might give that a try. There are some posts in the Apple Support communities that describe terminal commands to restart the Dock. I have not personally experienced anything like this in some time now. Years perhaps.
