can't read highlighted docs in PW from acrobat

hi,

the acrobrat pdfs that i have imported on my kindle paperwhite 7 are highlighted. the sections that are highlighted are unreadable on my kindle - they are completely grey, no text is visible.

is there a solution? is there a solution on kindle? i want to keep my highlights. if not on kindle, is there something i can do on acrobat?

thanks so much for your help!
