Clear data greyed out (Mi9T Pro)

[Janmiui]

Hi,
yesterday i installed the xiaomi.eu rom (20.3.12 beta) on my Mi9T Pro
I followed these instructions:

TWRP Recovery Zip DOWNLOAD or TWRP.ME

• FORMAT /data partition (NEVER wipe System or Persist!)
• Reboot in twrp
• Copy ROM to the internal storage
• Install ROM
• Wipe dalvik and cache
• Reboot
• done

The ROM boot well, but i can't "clear data" of any app, the clear data button is greyed out.
Today, i updated to 20.3.19 beta,
changed also twrp, Wipe dalvik cache, cache and reboot .... but i not solved problem.

Please help me !!!

At the end, i had to format data again
1) update recovery to the latest "twrp-3.3.1-32-raphael-raphaelin-mauronofrio.img"
2) format data
3) reboot to recovery
4) flash rom
5) flash "Disable_Dm-Verity_ForceEncrypt_01.15.2020.zip"
6) reboot to ROM

This rom has serious problems with encryption ⚠⚠⚠
In another device (Mi9 Lite), upon normal rebooting, he asked me for a password that I had never set.
I had to "format data" (from TWRP) without being able to backup data, because was crypted !

well, all the time, first of all we make a backup... after that we install recovery...
if it asks for password if you don't have one set to the phone, it means you need to update the twrp version

How could I backup if the data partition was encrypted with a password that I had never set?
Do you think that before do format data, I didn't try different recovery?

Exactly that is why you make a backup on pc... :/ anyway sorry I replied... Won't happen again
