Obect Error not acknowledgeable in 800xA Faceplate

We are having some trouble with standard MotorUni, MotorBi, ValveUni and AcStdDrive function blocks entering PriorityMode not acknowledgeable by the Faceplate.

The only workaround we found is disabling all alarms or disabling object error, and enabling everything again. Sometimes this doesn't work and we have to acknowledge it directly from the interaction window.

The PriorityCmd have all their corresponding text, but in the interaction window we get as if it was the default text.

What can be the problem?
