How to fix duplicated snippets in VS Code?

All of my snippets from rust-analyzer have been duplicating somehow. I started off seeing the appropriate number, then started seeing 2 of each, and now I'm seeing 4 of each. This doesn't happen with snippets from any extension besides rust-analyzer.

Anyone know how to fix this and prevent it from happening again?

Currently, you don't: This is a known issue with rust-analyzer. I'm fairly certain there's an issue open for it, but I can't find it too quickly.
