Cannot remove lower patch of hosting bundle

I just installed .NET 6.0.18 and am trying to remove the hosting bundle 6.0.16. I've tried the following commands:
remove --hosting-bundle --all-lower-patches --force
remove --hosting-bundle --all-but-latest --force
remove --hosting-bundle --major-minor 6.0.16 (will note that this option gives an error: "The specified version is not valid")

I've reset IIS and even rebooted the server after these attempts. However, both versions 6.0.16 and 6.0.18 are still listed after all these attempts. I've also attempted to uninstall 6.0.16 from the Programs and Features UI under Control Panel - all with the same results.
