Character-creator glitches

Dear Mojang, I have multiple issues on the character creator section in Minecraft. The first is whenever I choose a character to edit, every other character I'll tap after that will look just like the first one. The second is I have duplicate clothing items in character creator, and when I wear one the duplicate is also selected. I didn't play Minecraft for about two years or over, and when I came back these problems arose. Please help!
Note-I could not select my version, it is 1.21.41
