How to prevent rust-analyzer importing duplicate or wrong items?

Hi,

I'm using rust-analyzer in neovim (lunarvim) and it works almost fine.
But in some cases when I already have some imported struct or enum from my own crates or libs ( for example customized Result or Error ) rust-analyzer auto completion adds unwanted and duplicated struct or enum from other cartes like serde or std.

every time it happens I face unexpected error in my file and when I check on top of my file I find some unexpected use lines added there.

Sometime it is really annoying as it repeads several times during editing code.

So please help me find how I can prevent rust-analyzer from this action or at least prevent duplicate same name import?

Reproduce the issue in rust-analyzer through Neovim or LunarVim with custom Result or Error types and completion enabled. Check when completion adds unexpected or duplicate use lines from serde or std; done means the reproduction is explained and a way to prevent the unwanted imports or duplicates is identified.
