Biped texture not working, I followed texture template correctly

This is why they need to add official texture templates to MCreator. I literally can't get my biped texture to work right. I did LITERALLY EVERY SINGLE THING that I could find on questions on the forums. Cropped out the image to 64x32. It still didn't work. I followed the first template I found. The image already fit the template. IT STILL DIDN'T WORK.

Here is the texture (blurry due to the resolution, but you can see what I did)

And here is the mob:

It might be harder to see, but notice that the texture is stretched. Did they change the biped texture to 64x64 in an update or something without me knowing?
