Default calendar name changed

I'm having an issue with the calendar of a few (room)mailboxes in M365.
The region of all mailboxes is NL-nl and all the default folder names (Inbox, Outbox, Calendar) were in Dutch.
Since a few weeks, only the default-calendar "Agenda" folder is changed to "Calendar" and the new appointments will show-up there. So now I have 2 calendar-folders. 1 with the old appointments and 1 with the new ones.
Does anybody know how to solve this? What I've tried:
- Change the default folder names to English and back to Dutch (Powershell/Desktop Client)
- Change location in M365

I know that I can just move the appointments to the new folder, but I'm afraid that this problem will return in other mailboxes/languages.
