Formatting Date time picker not working

[Nannette Mori]

Jira8.13 data center

I am trying to format my dates for my custom date fields to

mm/dd/yyyy am/pm

04/29/2021 12:00am

the format I am entering is for the jira.date.time.picker.java.format

MM/dd/yyyy hh:mm a

the format I am entering is for the jira.date.time.picker.javascript.format

%m/%d/%y %I:%M %p

I am getting an error:  Invalid date format. please enter the date in the format MM/dd/yyy hh:mm a

What am I doing wrong here?
