Ghost files after clean install and database migration from 1.7.6.7 to 1.7.8.7 theme.css, core.js etc

[Dhaerow8]

Basically Im struggling with issues after clean install of 1.7.8.7 and database migration.

Files like theme.ss and core.js have their ghost version somehow.
If I remove theme.css from the theme folder obviously the styles are messed up however if I remove everything from it everything is fine like there was a cached version of it.

Same with core.js. I have an issue with cart not updating so I was trying to use the core.js from an old version but it wont take it into account.
It keeps using the "ghost" one. If thought I just created a file and named it core.js (empty file).

To deal with CSS issues I use css module as it has higher priority over theme.css. No idea what to do with core.js if I cannot replace it at all.

Prestashop cache is disabled, server cache is also switched off (debug mode) and tried flashing it multiple times.

I have realised that it works fine if I enable the cache on performance tab. 
Then it doesnt take theese "ghost" files into account.
However if I disable the cache there are still being used even though they are not visible on filezilla.
