IOS RetroArch app showing a lot more storage used than it really is

Description

I am new to RetroArch and i use it on IOS on my Ipad mini 6. I just discovered a bug that concerned the storage used on IpadOS. I put my ROMs in RetroArch folder to use them in the app. However, i have 7.57 GB of games only but when i go in IpadOS parameter > General > Storage, Retroarch show more that 30 GB of used space. Moreover, i cannot open to see what are the 30 GB because the parameter app freeze and is unusable after that.

Bisect Results

I don't know how or when it started exactly, but to install RetroArch ipa file with AltStore, i had to reduce the official ipa file size by delete some dylib files in the ipa file, some files concerning emulators cores that i don't need like mame. Because AltStore do not accept more than 300MB ipa file size.

My use of RetroArch is just import content by analize my ROM folder and play directly, i do not change anything else.
