I am experiencing the same issue. There was however an update which fixed the search (CU Nov 2019).
Still experiencing issues with setting the keyboard format for my users, all registry settings are telling that I am using Azerty but when a user logs in, they get 2 keyboard layouts (ENG is default while AZERTY was set as default for the whole image).
My users need to switch keyboards every morning now...
I installed the dutch language pack on the 1909 image and set azerty (belgian period) as only keyboard. Applied settings to all new user profiles and sysprepped the install.
When the desktop was deployed, every user has ENG as default keyboard and also an azerty as second choice. If i log in as admin I can only see azerty in my available keyboard layouts (via settings, language) although ENG is also shown at the right bottom keyboard switch.
Looking through registry settings I can only see nl-BE as a language and keyboard layout so I wonder where this qwerty keyboard is coming from?
