Can't use arena fights and training points from blood games reward to unlearn

Been busy for the past several days towards the end of BG season 1, so haven't done any arena or tavern fights for a few days except logging in and healing. Now the arena fight button is greyed out for me.
I thought there might have been a system check somewhere for been away or something, but haven't found it, does anyone know?

Also, I can't use the reward training points to unlearn a skill for respec, I can use them to train just fine, just can't use it to untrain on my older glads.

Ok, can get back into the arena now.
But those training points from the BG seasons rewards are still sitting there mocking me...

Seems like it's learning only with those points.

Ah, it's working now, training points spent, finally.

As you already figured out, this is working now.

Good luck in the Pit!
