The feedstock for e.g. r-sf has version r-sf v1.0_19 https://github.com/conda-forge/r-sf-feedstock/

However the r-sf anaconda homepage shows 0.7_3 which is a version from many years ago. Even worse, further down on this same page, the "platform installers" show different versions every time you refresh the page!

The API https://api.anaconda.org/package/conda-forge/r-sf has yet other, also incorrect version numbers, but at least they don't seem to change every second:

 "latest_version": "1.0_4",
  "platforms": {
    "linux-64": "1.0_4",
    "linux-aarch64": "1.0_4",
    "linux-ppc64le": "1.0_4",
    "osx-64": "1.0_4",
    "osx-arm64": "1.0_17",
    "win-64": "1.0_4"
  }

Could it be there are many old versions of this package lingering around in the database, that somehow get precedence over newer releases?

The same happens for e.g. this package: https://anaconda.org/conda-forge/r-terra
