Weird teleporter problem

[peach freak]

Hey. I made a teleporter, so I decided to use a teleporter texture for my floor texture. But when I used the red teleporter texture, it got split into 4 smaller parts. Here's what I'm talking about :

Is there any way I can make it so it is just one full teleporter tile? I've tried everything but can't find a way to fix this. Thanks!

Move the sector so it's perfectly aligned on the 64-unit grid.

It is not a glitch, all flats are aligned to the 64 pixel grid.
You could try to fix it like this:
If it is the only teleportor, you could try shifting the entire level so the teleportor is aligned on the 64 pixel grid.
Or you can make the teleportor a 128 X 128 square if the teleportor was centered on the intersection of 2 64pixel grid lines.
