CSV file a WordPress export problem when setting up for a translation

I have a problem with working my way around starting a translation of a CSV 2.0.0.0 file (Wordpress export).

Excell shows me 12k lines of code + text and SDL Trados Studio 2017 SR1 seems to only be able to get some 1000 words.

In editor mode I get both source and target full of text with source consisting only of numbers of lines and target consisting of some of the code+text

Please advise how to proceed with this one. 

 

 

PS I should mention that had also problems with XLIFF exports .
