Do you have the env variable [`JULIA_PKG_PRESERVE_TIERED_INSTALLED`](https://docs.julialang.org/en/v1/manual/environment-variables/#JULIA_PKG_PRESERVE_TIERED_INSTALLED) set? Otherwise the default _should_ be to install the latest version, assuming it doesn’t conflict with another package, and assuming the registry is up-to-date (and the registry will by default update on the first pkg operation of the julia session, or when `update` is called).
