Question on CMP and deleting missing dependencies.

Still trying to learn this stuff. On my list of missing dependencies in CMP, there are a bunch of them that show my number and name as the missing dependency. I guess that possibly I made a session or route and then deleted the session, but am not sure. My question is, is it safe to delete this items from the list, since they show my name and number as the unknown kuid, but then there are a long list of other kuids in the same asset. I just want to make sure I won't delete all of them.
