GZDoom Builder Grid texture glitch

[Screwdriver McDollarsigns]

So I've been working on a wad for some friends and myself to play around with. I decided to do some edits to some textures and everything went fine at first. But I finally went in to change one more texture (And I want to stress, all I did was change the swap the texture for the edited version and added it to the texturex file.)

And now my grid looks like this, Any ideas how to fix it?

It's really just an aesthetic issue, and it's limited to this wad, and I have no idea what happened.

Looks like you set the texture as the grid background. Just click on the grid icon in the bottom right, then "Customize..." and disable the background image.
