Hi There,
Thanks for writing in!
There is no such official; plugin recommendation, due to the fact that there is no accountability of issue.
I will try to help you on this through custom CSS if that works for you.
Please add this CSS to your theme option -> CSS and let us know if that works.
.wpb_wrapper .flex-direction-nav a {
height: 20px;
width: 20px;
}
.wpb_wrapper .flex-direction-nav a:before {
font-size: 16px;
}
Hope this helps!
This is something related to a custom CSS, may need further adjustment.
