Wds loop?

I have 2 Ap bridge mode, clients with station wds, in this days I’m having problems with 2 clients, userA from Ap1 its getting its “gateway” from UserB who is in the Ap2, I tried differents stations mode, in the Mk core I put somre filters bridge, horizon rules, and firewall rules, tried changing Ip on both users,rstp, nothing works.

Any clue?
