Populating private registry tagging problem - Windows and Linux clusters

I’ve populated an air gapped Artifactory docker repo using this guide:

The Windows images were saved with the tag imagename-windows-1809 and are uploaded to the registry with the same tag.
Then when uploading the Linux images they’re being tagged as imagename-linux-amd64.

Then when trying to add a windows node I get an error that the manifest for rke-tools doesn’t exist because it appears as rke-tools-v0.1.66-windows-1809.

How should i proceed about fixing this?
