The new round shields are losing their dye effect when you have it in the vault, load your vault after logging in, the shield is socketed, AND has a crystal in it. LOL Hope that makes sense. The inventory icon, description popup display, and the name loses the dye signafiers but it is still listed under effects and it seems other players can see it dyed in the popup when linked to others.

Removing the crystal(s) socketed into the shield rectifies the problem and the shield reverts back to being dyed but this should probably be sorted out.

HTH
