Words not correctly space separated

In so many lessons I have problems with space separation and it gets quite annoying. See for instance the picture below of a sentence from a lesson I am learning right now. What’s the deal here? I don’t think the origin of the problem is in the source material, as when I read through the pdf or epub I don’t see any spacing issues. But when we import into LingQ, the spacing gets all messed up, words get glued together.

If I’m correct in saying that the problem is with the LingQ software, then it really needs to be addressed, as it’s a pretty foundational bug.

Example for those who don’t know what I’m talking about:

If I’m wrong, and the problem is indeed with the source material, please let me know!

Can you send that file you imported to support(at)lingq.com? I’ll look into it.
