The number of installed keyboard layouts from the Settings menu & the taskbar don’t match, and a layout can’t be selected

The issue described in the title can be seen in the picture. The layout US – Norman – PL, which has been created by me using MSKLC can’t be selected. The other layouts can’t be eliminated.

I would appreciate help with:

  1. Selecting US – Norman – PL
  2. Eliminating all other layouts

Thank you
