This seems like the same error from this topic:
https://forum.bisq.io/t/error-you-dont-have-an-arbitrator-selected-except-i-do/3337

To quote Manfred:

@ManfredKarrer

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.
