Error importing comics

This is the error, I am getting.

Error importing comics
There were errors during the import process, please, check your files and/ or network connectivity - error: The operation couldn't be completed.
(YUnableToCreateThumbnails error 100.)

All the files I have are zip files. Some imported perfectly fine, but others are not importing.
All the files are locally stored in my iPad.
I also use different apps such as Chunky comic reader, Tachimanga, panels.
Those three apps imported the files perfectly, I just don't know the reason why it is happening like this, if the other apps are perfectly fine

Send me some of the files you can't import.

Hi, how to send the files to you

You can find an email address in the contract section of this web or you can use the Help section in the app. If the files are too large just share a link to a cloud service.

Hi, I mailed you the drive link. Can you check it?

I replied in the mail, but it is a problem with bad image files inside, there are lots of bad images with .jpg extension. I sent you some screenshots.
