Black text showing up as white

I downloaded a set of slides when I used my Adobe Acrobat to open it, and the black text is showing up as white. In the screenshot below, the same file is opened with Google Chrome (left) and Adobe Acrobat (right).

If I try to edit the text color, the text is set to black (but obviously, it is showing up as white.) If I try to set it to other colors (dark gray, green, red, etc.), the text shows up as those colors, but when I change back to black, it comes up as white again.

Does anyone have any idea how to fix this? Other pdf files are showing up correctly, just this one.

Much appreciated!
