Hello, I noticed that sometimes when I import books, the whole text is divided into “little paragraphs”. So far when that happened I just downloaded another edition of the book be it different publisher, year of publishment, so on. Today I just converted epub to pdf, and it helped, duh, the solution was this easy all along. Hope this helps someone.
Here’s how this looked:
That is good to know. I usually prefer uploading directly from .txt. The fact is that I don’t check every lesson straight away, and when I realised paragraphs have been cut that way, it is too late. 
There has to be some encoding that it is not well digested from the system. Because sometimes this happens from a .txt when I don’t see any weird stuff on the text, but when I upload it to LingQ a few things are messed up. Go figure!
I copy and past one chapter at a time. That way the paragraphs stay intact and each chapter is a single lesson.
