Issue with subpath globs?

Running ls-exports against my react-utils package, it's telling me it can't resolve any of the subpath exports I've defined.

Example: https://github.com/Twipped/react-utils/blob/1d81497bd08b9b7450ac66880f6c3f2e58b8b6a3/package.json#L50

!! Errors:
┌─────────────────────────────────────────────────────────┬─────────────────────────────────────────────────────────┬───────────────────────────────────────────────────┐
│ “./hooks/*”: ./src/hooks/*.js does not appear to exist! │ “./quick/*”: ./src/quick/*.js does not appear to exist! │ “./ui/*”: ./src/ui/*.js does not appear to exist! │
└─────────────────────────────────────────────────────────┴─────────────────────────────────────────────────────────┴───────────────────────────────────────────────────┘

Am I defining these wrong, or is this a bug?
