Track changes not changing font

Working in version 6.0.3. With any calc document I have, when I go to Edit>Track Changes>Record Changes and then I make changes to the document, only the border of the cell changes color (from black to red). The font does not change color as I am expecting it to. Is there a feature that I am not enabling or is my technique not correct? Another user of this feature states that when they used to use this feature, the font would change but doesn’t anymore.

The font does not change color as I am expecting it to.

Why are you expecting the font to change colour?
