How to delete corrupt archive?

We've been having some storage issues and have finally got those resolved. However, we're stuck with a particular archive that has some bad entries in it. I've tried deleting the bad backups (incrementals in this case) but it just says they cannot be deleted.

Any suggestions? We are using B&R 11.5 VE with deduplication running on a storage node. It seems that this is the first archive the catalog tries to 'catalog' as well and it stops and never touches any of the other archives.

Running build 11.5.37687.

The error message I get is:
