Have they tried to create a Type 2 or 3 flag? Creating a Type 1 flag shouldn't prevent them from also creating a higher level flag on the same user. See below from theymos:
These limits are in place:
- Per 180 days, you can only give 1 flag of each type to a given user. So you can't give someone multiple written-contract-violation flags in 180 days, for example.
- Globally, per year you can only create 1 flag per activity point you have, but at least 1/year.
