Cannot delete branch after rollback (time travel)

hi all, is anyone else having this issue where after rolling back a branch to an old state, neon will autogenerate a branch for the existing one that was rolled back (i renamed it) and then you cannot delete the generated branch? like as in the main was the existing branch, then it got rolled back to a previous version and main_old is the copy of the branch at the moment it got rolled back (present) and then its not possible to delete it i get this error
