Date in report server

Hi everyone,

I have report in PBI desktop with imported data and plots work fine. I saved this report in Report server and there my plot doesn't show properly date. I exported data on both desktop PBI and report server and they are identical. 

In report server, date is shown in tooltip as NaN.NaN.0NaN, where my date format is dd-MM-yyyy. 

What can be an issue?

Regards,

Yerkhan
