Your cios 249 is stubbed. You should reinstall it using either modmii or
https://wii.guide/cios.html
Careful not to install a duplicate of your 250 to slot 249, it doesn't really matter much what u have where so long as you have base 56 in one slot and 57 in the other
Edit: btw a duplicate cios isn't dangerous or anything, just pointless
Edit2: if u ever want to check if your mods are optimal, you can drag and drop your syscheck.csv onto modmii.exe and it will tell you what to do. In your case it will recommend some additional minor things, but really your cios249 is the only substantial thing worth mentioning
