[Events +] Cannot delete test event payment/RSVP Events+/MarketPress

Me again :slight_smile:
Having almost successfully testing buying a ticket using Events+ and MarketPress (I got a 404 on return from PayFast), I went to delete the test payments and cancel the RSVP on the event so I can start again.

Unfortunately it is still saying I have paid and I cannot do my usual "cancel attendance entirely".

Thoughts?
