Users have an error in Power BI Service, but dev can't replicate

[Henrymc]

Hello, 

Has anyone experienced an issue like this:

I have a user in the Power BI Service who says that a particular filter in their report is not working (e.g., not filtering what it's supposed to). However, when I go to the same report in the Service, I'm unable to replicate her issue. She's provided screenshots showing the filter condition and the item that is not being filtered, but I can't find any actual issues in the report itself. 

The filter is a calculated column that takes the time frame and sum of the metric for that time frame as arguments, but again, I'm not able to replicate the user's problems. 

Any suggestions for troubleshooting this?

time zone issues? browser cache?
