This happened to me a few times now. If I make an annotation, it ends up being too much to the right.
It’s happening to me when I test it, too. Let me find out what’s going on.
Updating to add ticket link: Manual annotations don't stay where they're drawn · Issue #383 · WildMeOrg/Wildbook · GitHub
This is now fixed in GiraffeSpotter with a wider release coming to Wildbook 10.4.0.
