Question on front card not visible

I have been having this problem with the Netter Anatomy cards; the question is not visible on the front card. The answer comes out well. This was also true when using the Windows platform but after changing the text color code, the text appears. Can’t seem to find the card css(?) on the mobile.
Any help will be appreciated

That card template can be edited on mobile by tapping on the gear/cog in the bottom right of the study screen, then scrolling down to Card Template. It might be worth trying both dark and light mode - deck authors sometimes don’t test their styles with both modes.
