WADS replacing floor textures not displaying correctly...

[Sun]

I put the names in the WAD correctly, and for some reason, this happoenes to the floors. It doesn't happen in gfzgoodf.WAD, but when I try to edit a floor in that WAD, the same thing happens to that floor. WTF am I doing wrong?

For floor and ceiling textures, you must tell XWE to convert to a Doom Flat.
