When you change the skin of Minecraft Java Edition from the site minecraft.net, you are offered a character model, that is, choose Alex's arms or Steve's arms.
Alex's picture changed to her new skin, but Steve stayed with the old skin (no beard).
The first picture shows Steve's new skin, it should be on the site.
