Transitions disabled when my nav section is on

Hello!

I am completely new to webflow and this is my first my project so please bear with me!

I have created a grid section with images that have a hover roll over effect on them (all working fine and dandy), however when my nav section is enabled the hover transitions in the grid section no longer work. When my nav section is turned off the hover transitions work fine.

Does anyone have any suggestions for me?

Please and thank you!
