I am receiving the message in a pop up 1Password is damaged and cannot be opened. Delete and download again from App Store. This had gone away and now is back with recent update. It pops up so often ...
Thanks for posting the screenshot. You can remove the extra copy of "1Password for Safari" that has App Store Download in the Kind column on the right:
Keep the copy that has Application in the Kind column. Let me know if you run into any issues.
