Image1 and Image2

In Calc cells with Conditional Formatting (created using the "The Formula is" option), although the format looks correctly on the screen, when I try to select them and Copy-Paste, the resulting "image" does not reproduce the Conditional Formatting of those cells. Other Conditional Formats, on the other hand, reproduce perfectly.

Image1.jpg shows how it looks on the Calc screen (To capture this image I used the "PrtSc" key on the keyboard and cropped the image with an Image Editor).

The Interval C3:D10 have the following Conditional Format:
Condition 1: Cell value is less than 0 Apply Good style (Light green background)
Condition 2: Cell value is greater than 0 Apply Bad style (Pink background)
Condition 3: The Formula is Y($C3=0;$D3=0) Apply Highlight style 1 (Both cells black background)

If now I select the interval B2:D10 and I copy it (Ctrl+C) and then try to paste it (Ctrl+V) in another application (For example, in an image editor or in a WhatsApp message) what is pasted is Image2

As you can see, the result of Condition 3 (the one with the black background) is not copied.
