I just found the solution. You just need to increase split size in output for epub. It works now.
I wonder what split size affects. Why keep it at 260kb? Is it ok if I leave it at 800 or will it have some negative effect?
But still I managed to get epub, but mobi still gives me nothing.
I even added the created epub to library as new book and tried converting to mobi and still nothing.
