Changes to user settings from the admin panel are not propagated

If you change the display name of a user from the admin panel (right > edit> change "display name"), this is not applied to the user.

Steps to reproduce:

• access to the admin panel
• double click on user "user1" with an active profile (or right-click > edit)
• modification of the "display name"
• save and close
• logout from the admin panel

Expected behaviour:

• login with the user "user1"
• the displayed name is changed everywhere.

Actual behaviour:

• login with the user "user1"
• the displayed name has remained unchanged (as identity, as the main folder name @XXXX and in the settings)

Note:
If the display name is changed on the admin panel via the right-click > Edit > Main > display name, the change is applied correctly.
