No manual mode after leaving dashboard

We have several UR16 and using the dashboard for remote operation. Since we have been using this, it is no longer possible to switch between auto and manual mode via the TeachPendant. We always have to use the dashboard with “clear operational
mode” statement. In the menu of the TeachPendant the change of Automatic/Manual is missing.
We do not have an idea for that behave.
I am grateful for any tips.

P.S. We did an update to the latest Polyscope version, but no effect
