Enter date in format dd-MMM-yyyy

Hello,
I am new to ODK, which I am using through the OpenClinica.

1. What is the problem? Be very detailed.
I am trying to change the Appearance of a Date question to allow dates to be entered in the format
dd-MMM-yyyy (for example 01-JUN-2021)

2. What app or server are you using and on what device and operating system? Include version numbers.
OpenClinica 4 Stack 13.3.1 (Sorry I don't know which version of ODK it is using)
Microsoft Edge Version 91.0.864.71 (Official build) (64-bit)
Microsoft Windows 10 Pro (Version 10.0.19043 Build 19043)

3. What you have you tried to fix the problem?

In the Appearance option, I have entered the following formats which have are ignored.
'%e-%b-%Y'
format-date(.,'%e-%b-%Y')

4. What steps can we take to reproduce the problem?
Add a Date question to a form and apply the same formats.

5. Anything else we should know or have? If you have a test form or screenshots or logs, attach below.
