How to reproduce the issue

It happens in both my config and [kickstart.nvim](https://github.com/nvim-lua/kickstart.nvim).

Expected behaviour

Each snippet shows only once.

Actual behaviour

Same snippet appear multiple time cluttering the view. Used plugins are nvim-cmp and lusnip.

The minimal config used to reproduce this issue.

-- kickstart.nvim

Hey :wave:

• rustaceanvim doesn't implement (auto)completion. Issues with (auto)completion either come from another plugin or rust-analzyer.
• For future reference: kickstart.nvim is not a minimal config. rustaceanvim provides a template you can use.

For me, this was an issue when I was using mason to install rust-analyzer. When I installed rust-analyzer via rustup component add rust-analyzer the snippets work as expected.
