I have the same issue. In fact, the issue has been around for me since beta. I assumed it was going to be fixed when the game transitioned fro beta to "live," but that didn't happen.
From what I've noticed, the problem only occurs when I switch from between Entrenchment and "Vanilla." My guess is that this is happening to you as well. My workaround? I no longer play Vanilla, thus I no longer have an issue.
