Can't refund keystone (Oracle Druid)

I believe this is due to an interaction between the keystone "unwavering stance", the oracle passive "entitled realities" and a from nothing (Bulwark) diamond.

I cannot refund the keystone "unwavering stance" within the range of bulwark.

I have a similar issue. I've refunded every passive that I can, and still cannot unallocated Pain Attunement, which was initially connected with Controlled Metamorphosis Diamond.

Did you find a fix for this?

For anyone experiencing a similar issue, I was able to fix this by refunding enough nodes so that I could path to the keystone and unallocated it the in the usual way.
