Dt swiss freehub ghostpedaling

Hey, I need some help!

I recently bought a replacement for my DT Swiss ratchet hub (11speed) as the old one was getting old. Also bought the correct DT Swiss grease that they recommend. However, since then i have had an issue with ghost pedalling, I tried cleaning everything and regreasing it again, but have had no luck.

Has anyone ran into this issue, and what do you think i could do to fix this, not really willing to give a bikeshop a lot of money for such a little task. Please ask me questions if you are missing any informations.

Thanks!

Is it the EXP or two ratchet system?
