Reformat sdcard on every reboot in MIU13

I have an Android 12 with MIUI 13, Xiaomi Redmin Note 11 pro 5g. sdcard works flawlessly, configured as an removable/external memory. I reboot the phone, and it asks me if I want to use it as an internal or external memory (portable). If I choose external, the only option I have is to format it and loose all my data. This is a lot of overhead: copy old data, reformat it and copy again backup up data. I already hat to do so when I upgraded from MIUI 12 to 13. I don't desire to do this every time I reboot the phone. Any hints to avoid all this fuss? I've checked with fsck that the partition has no problems.
