Deactivating node.js

I’m trying to deactivate node.js from PLCnext following the steps on screen but the following error message appears during the procedure at PLCnext Store step. Error400 2

Hello rrichter, please first check with your WBM (FW >=2020 ) if on your PLCnext is a license.

To do this, open the WBM, select the category Administation → License Management. In the table you can see all licenses on your device. What irritates me is: that there is no license for the app Node.js at all.
Do you see the one Node.js license in your license pool ?
