Glitched migrator cape

This bug affects previous versions, <1.16.5, I just couldn't put it in the "Affects Version/s" tab

When the migrator cape is selected, it shows up, however it doesn't have the correct texture a migrator cape should have. This issue not selective to only me, as my friend has also encountered this issue. 

This issue carries over from Lunar Client (PvP client) and vanilla minecraft.
