Wrong decimal seperator

I'm struggelig to get Power BI to show commas as decimal seperator. I haven't had this problem before, so I'm quite pussled to the cause of this.

In "edit queries mode" values show correctly eg. 5,3 - but in data view it comes up with 5.6. Both my regional settings in Power BI and my Windows settings are set to Norway - so comma should be the default decimal seperator.

Hoping someone can help.
