Leg Dupe glitch on Skin

Alright, so a little bit ago, I made a new Minecraft skin by taking the cloths off the one and putting them on the other in Paint.net, (I have done this before and it worked). When I applied the skin on Minecraft Java, it was fine, so I applied it to my Bedrock profile. When it gave me the options to choose between the Alex type skin and the Steve type skin, I choose the Alex because that's what my skin model is based off of. When I looked at the skin, the legs were move about one pixel over and the legs were all messed up because it duped the right leg. I have tried fixing the skin, download the skin from Name and other stuff but I can't get it right. Is there anyway I'm able to fix this?

First four images is the skin that is glitch, and the last one with the blank background is the one from NameMC.
