Leaving a server up for ~24 hours with a world and then returning to it and spawning new camels will cause all of them to perform this behavior. Commands will just trigger it whenever since it's setting the problematic value. This would be more closely related to an entity issue than command.
After re-testing it appears to only be caused by the command itself.

I added a new screenshot of it in base Vanilla. Forgot I was using Fabric on one of my installs.
