Hi Stefaniay,
That sounds like good news.
It seems to be related to synchronization, please continue to use as normal and watch to see if the problem reappears.
None of Microsoft's support pages specifically mention syncing keyboard layouts with installed languages, but only "language preferences" are mentioned, which would be a great find if confirmed.
If anything is unclear, please do not hesitate to let me know.
Best regards,
