So this "!" icon keeps pinging me that the Warlord has got something knew, but it is always at the helmet section even though I already dismantled them the "!" icon keeps pinging it is annoying as hell. Please help.

Here are the link pictures of my annoying problem:

After in the helmet section:

And everytime I go out again it keeps showing the "!" icon even though there are NO new helmets
