Ok, so here's the thing....after talking to an actually helpful CS person  when you click on that 'take action - receive fee credit' link it opens another page AND if you have marked item as paid, it then says 'item has been paid - cancel the dispute' so all good with mine.

Here's another fun tidbit - had a customer buy 17 items.... then decide to purchase them on my website instead  so cancelled these, and she agreed to the cancellation at her end. All transactions coming up as cancelled in resolution centre but no green tick of fvf refund on my selling page. New system I am told is those refunded fees don't show until your monthly invoice is released.  They are there as credits on my invoice but not showing on seller page. Why???

Ebay CS told me there are still many problems with the new dispute system and this is just one of many 

Ah well.....I guess it wasn't broke so SOMEONE had to go and "fix it"
