Dialog 'Add library' does not show all Lenze libraries

What happens?
If a library is added in the library manager, then the dialog 'Add library' in the folder 'Lenze' shows only the library 'L_SlaveConfig_i500'.

When does the behaviour occur?
The behavior described above occurs when in the dialog 'Add Library' the button 'Display advanced libraries' in the upper right corner of the dialog is disabled (the button is displayed without a blue frame).

Which products are affected?
PLC Designer V3.22

Short-term measures:
Activate the button 'Display advanced libraries' in the dialog 'Add library'. Alternatively the button <Advanced> can be pressed in the dialog and then the library can be selected. 
A new installation of the PLC Designer does not help, because the PLC Designer setting is stored in a separate file, which is not uninstalled.

Evaluation / recommendations:
In the dialog for adding libraries to the PLC Designer project the Lenze libraries are not shown. Under 'Short-term measures' an applicative solution is described.
