Deviation between unpublished and published report

[amdosa]

Hi, 

First: I'm a newbie PowerBI, so I hope you guys will be understanding of my lack of competence. 

My problem is that my data in my PowerBI file works superb while using the desktop application. However,  the published version shows different data than my desktop version.  

I attached a snip from both the report from powerbi.com and from the project file, see below. As you can see the from the online version data is registered in month 1 and 10. According to the project file, data is registered in month 1 and 2, which in this case is correct. The problem seems to solely happen when i'm working with dates. Sadly the project file contains a lot of sensitive information, and I am therefore not able to share it here. 

Could anyone help me out a bit here?

Some additional information: My powerBI application is in norwegian, could this maybe cause the problem?

From project file:

Does nobody have a clue here? 

Would really appreciate all the help I could get.

So, you are saying that if you refresh your data in Desktop and your visual looks like the bottom image that if you then Publish the report to the Service and then go look at the report (not a dashboard tile) that your visual in the Service looks like the top image?

That is correct.
