Bugs on mirrors

[LasmGratel]

When I select the mirror in "Launcher" panel(I use bangbang93)
And I try to download a game
Then it shows the launchermeta too
picture here:

And it should be bmclapi2.bangbang93.com, because sometimes I(and lots of China players too) can't visit launchermeta.mojang.com
In Bangbang93's Blog, he said that it supports the new staging system.
So can you change it?
