It may affect more of the pieces then just these 2, but both of these pieces has a section of it that can’t be dyed with Moss Dye.
You can select a Moss Dye for the section and apply it, but it will not stay, and as soon as you change from the Dye screen and go back it says “Dye Remover”. It may apply to more than just Moss Dye but it is the only one of the 200+ Dyes I have that had the issue for me.
