I have a custom date field (Join Now Launch Date) and every time I enter a date of 11/23/2020 and refresh screen it is overwritten to 1/23/2020. I've tried making sure the date pickers and other fields are setup in advanced settings (although I've never had this problem with any other date fields until now) But I did reference the below article and that didn't work either.
You should be able to adjust this within the advanced settings.
You this page as a reference for the format setting when updating this value.
