Cubase 9.5 mixdown audio quality is poor

So i’ve just made a new track and wanted to export it but i noticed that the audio quality is really poor. It kinda sounds like when you record audio that’s coming out of some speakers with your mobile phone (especially the snares). I’ve tested exporting it in different file types. Also i’ve upgraded from 9 to 9.5 to see if it would export better. Export settings are all on default. All help is appreciated.

Edit: If i export every track individualy this problem doesn’t seem to occur.

Thank you in advance
