Hi @CAnoop,
The only thing I think about regarding your question is that one of your folder has not been properly converted in ext4
Make sure you try them 1 by 1 using "Repair" or "Change" functions
If you have an error message saying you can't convert, then try using other functions of TWRP, you should be able to convert them all 3.
Also, According to what I read in this forum, the "Android actions-> Full Factory Reset -> Wipe data" action is not always necessary.
Good luck !
