Note
This issue happens because your server and/or client is modified. This is a known issue with Paper https://github.com/PaperMC/Paper/issues/8689.
So me and my friends play on a paper server, but sometimes when we die we lose the outer layer of our skin even if it is toggled on. To fix it, we have to toggle off and on anything in skin customization.
Paper is a modified server. See https://github.com/PaperMC/Paper/issues/8689.
Thank you for your report!
However, this issue is Invalid.
Your game, launcher or server is modified.
If you can reproduce the issue in a vanilla environment, please recreate the issue.
Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.
Any plugin issues need to be addressed to the creator of the plugin or resource pack.
If you have problems on large servers like Hypixel, please contact them first as they run modified server software.
