I think you mean to type 12:00 AM and not 00:00 AM because blondie63 is correct that you cannot type or enter 00:00 AM.
I entered a start time of 12:00 AM and an end time of 11:59 PM and it seems to work. HOWEVER, the store is technically closed for 1 minute every day – not idea but there is a bigger problem that I will be posting about separately. Hoping for a swift fix. Thank you to the developers!
