Lit to Epub conversion spacing error

I recently converted a book from Lit to Epub but the conversion carried over the spacing errors from the original file, is there a way to improve this? Is find and replace an option or would that remove the paragraphs as well? Below are the first two or three paragraphs and the rest of the book is the same. I can go through the book manually but there are 158 html files. Any help or pointers would be appreciated

Nevermind, read help file and realised I hadn't enabled heuristic processing :(
