Lately I've had huge issues with Calibre

. When I try import multiple Manga books to my Kobo Forma (I've tried with 2 different Kobo Formas, happened to both) it just doesn't add all the Manga's/Books I select.
When I add them individually e.g. Volume 1 imports just fine. When i proceed to add Volume 2 it suddenly removes volume 1 from the device (that's what Calibre shows, that its not stored on the device after I import Volume 2)
Thing is, this only occurs with certain manga. I have this issue with Vagabond, Jojos Bizarre Adventure Part 8, Dorohedoro.
I havent had issues with importing all 6 Volumes of PTSD Radio.
Mind you this has nothing to do with storage space, it is a fault on behalf of Calibre
Ill import a code of line from the debug mode where it shows that it skips files

The process of what i do is download the pngs/jpegs through HakuNeko, zip them into respective volumes, run through KCC (Kindle Comic Converter) and then through Calibre and then add the metadata. I also have CalibreExtended in order to export as kepub so i have all of the features.
WHAT CAN I DO????? any help is apprecaited!
