"You dont have an arbitrator selected" - yet i do. please help?

[6wAotI]

I am getting this message on half of single altcoin offers. For example Siacoin, in the picture. One offer i am seeing i can buy from, and the other is greyed out asking me for an arbitrator. Whats the deal with this?

This seems like the same error from this topic:

Error: You don't have an arbitrator selected (except I do!)

Thought I’d report this weirdness. I’m looking at an offer that is greyed out (offer to buy SC). When I click on it I get the error “You don’t have an arbitrator selected”. Interestingly enough, this message does not occur on an offer to sell SC (from the same peer) - the trade is not greyed out and appears available to me. I currently have two arbitrators available (both selected): swfmg… and 3b7cf… That must be some sort of a funny bug that is causing this. PS: see my other issue as well…

To quote Manfred:

Error: You don't have an arbitrator selected (except I do!)

Ah I understand now. He has created the offer when I was the only arbitrator. Now there are 2 other arbitrators and as he has only one which is not active anymore there is no match of the arbitrators between maker and taker. I will try to contact the peer to let him know to remove/re-create the offer.

So basically you can’t take that offer. The arbitrators for that offer are not available anymore.
