Why does my full page menu bar load and blink for a moment before showing my actual page?

My nav bar is a full page animation. I’m having the issue of when my page loads, the menu appears for a moment and blinks before it goes to the actual page. This menu has has had no many issues and it’s finally almost there. Any thoughts on how to fix this? Thank you

maybe because in the animation of “Open - Nav Bar Menu” the hide/show function at the top of the inital states is missing? Try it out.
