Punch of lines highlighted when search in project using vim-ripgrep?

[SalahuddinAsh]

I'm using NVIM v0.3.2

When I search for a word in the project using vim-ripgrep, sometimes a punch of lines (mainly the lines visible in the right most window) are highlighted. This doesn't happen everytime. To get rid of this highlighting I should move the cursor on every line of the hightlighted ones, or jump a page down then back up and usually the highlighting gone.

I really like this theme the most, but this issue annoy me a lot. How can I solve it?
