Everyone’s situation is different, but I got around this problem, for my situation. I wanted to add two tags (single and strawberry) that would lead to a single item, so I added a new tag that combined both those catagories, (eg “singlestrawberry”) and selected that newly created tag. Bit annoying, but it worked for my needs. Just FYI I had to log out and back in again for the tags to reset though.
