Alex and Steve Skin

So everytime when I log on on 1.16.1 or 1.16.2 It always show alex and steve skin. When i go back to 1.8.9 It shows all skins even mine. This also happen with badlion. I don't understand what to do. I already read the support logs. Nothing help. I also try to to ask the mc discord server community. No on responded or knew what to do. If you could help me that would help a lot. Thank you!

Seriously - Jay
