Search No Longer Highlights in Blue

Hi, this is my first time posting, and I'm having trouble with the Search function on Adobe Acrobat. You can see in the image below that when I use the Search function, it no longer highlights the text in blue; it "highlights" the text searched by only changing the font color to navy blue (please see the word "promotion" on the second line below and contrast it with the rest of the text). It's very difficult to find anything this way, and everything I've seen implies that the Search highlight feature is not customizable. I'd love some help with it if someone could offer advice. I'm using a MacBook Pro. Thanks in advance!
