Too many tags in source text on studio - how do I solve this?

Hi all

This has happened to me before - after uploading the source text to studio 2017 and opening it in the editor - the source opens with far too many tags - so if the text in the source is bolded - instead of having bold tags for a section of text every single word is tagged - making it hard to read and impossible to use language cloud or translation memory because they also come up heavily tagged. As you can see  - it is ridiculous :-). Any help appreciated
