Microsoft List changing from am to pm

Hello all,

I have an issue with a Sharepoint List I created.

I have a list view which users normally edit in grid view. When they add a date like 08/12/2024 12:00 a.m.

It changes to 08/12/2024 12:00 p.m. and it only happens with the grid view.

It also happens from p.m. to a.m.

The problem started with the new look that List has since about a month ago. Has anyone encountered this issue before?
