Doors Are Glitched in 1.4.4?

[That Anarchy Dude]

I am using SMBX 1.4.4, and the doors are acting really weird.
I couldn't find anything about this issue anywhere (including within these forums).
What's happening is the door disappears when I try to go through it, and I have to press up to go through the now invisible door before it will warp me.
What's up with that?
Am I doing something wrong or are they just flatout glitched now?

You are probably doing something wrong as i have never experienced this kind of glitch in 38A. Just upload your level and i will see whats wrong with it.
