Colors disappear, when printing Power Bi report

Hi,

I have created af Power Bi report with a matrix visual.

In this matrix, I have used conditional formatting on the values in my difference column to highlight negative values in red and positive values in green:

however, if I want to print the report page, the colors disappear and all cells have a white background:

If I export to PDF, the colors stay.

How do I print directly from Power Bi without losing the colors..?
