Teams shows working hours incorrectly, e.g. 15:00 as 3:00

Hello,

I have changed in bulk via PowerShell for all users in Microsoft 365 tenant - working hours from 8:0 to 16:00 (Central European Standard Time).

I have noticed that in Teams the working hours have updated, but shows now 8:00 to 4:00.
This 4:00 looks like 4 PM (for example, for another user I set 15:00 and it shows 3:00 (sort of like 3 PM)
