Maybe also swapping the two relays over (with the necessary reprogramming) would show definitively whether the problem is within the particular relay or not?
Personally I have a suspicion from all the various postings e.g. about electrical storms affecting the BDR91 that the settings stored in its non-volatile memory can get corrupted, and doing a factory reset fixes this (at least until the next time).
