Dates show as (Blank) in app.powerbi.com, but not in Desktop

Hi,

I have a problem with a report where on the app.powerbi.com service, it continually loses it's date reference. It replaces every date reference to "(Blank)".

It does NOT do this in the Desktop version.

When I publish it to the app.powerbi.com site, it keeps the date until you move to another report, then back again (or press the refresh button).

The date table is being pulled from the same server on a different database. However, it connects and pulls data fine.

Has anyone else had this problem? - Highly annoying!!!

Thanks,

James
