How to reset Workers (GPU) after removing it (them)

Hi together!
Im using HiveOS in latest version.
I had to remove two of my six cards and now HiveOS Manager is telling me, that two cards (the missing cards) are red.
How can I reset it, so that only cards are monitored which are in the rig.
(The list of GPU hast four lines, which is correct, but the overview shows 4 of 6 Cards green, and 2 red recangles)
Has anyone an idea how to fix this!
