Weird Texture Bug with Box BSP to Static Mesh

Hello I’ve discovered something odd while doing one of my Udemy courses. One of the steps was to create a floor out of a box geometry. I resized and converted it to a static mesh. Doing this was so I could apply a texture on it properly. However out of some weird occurrence I cannot figure out why the static mesh has a red this coloration to the texture.

Here is what it looks like

Is this a bug? I am using 4.20.2 btw.
