Hyphenated last name support

I am trying to update a profile in Internet advancement (sent there by scoutbook). I am unable to save the update (OA Ordeal date) and receive an error indicating that a hyphen is not allowed in the name field. The member has a hyphenated last name which is already in their profile. Any thoughts?

We have notified the developers and they have confirmed it is a bug.

Any advice on how to add OA Ordeal date for this person in the meantime?

Unfortunately you will need to wait until the bug is fixed.
