Hey @Lon_Baugh,
With the launch of Roon 1.8 Build 831 there were a few changes and improvements to the Versions display and “Make Primary” version functionality.
If the albums are already grouped in your Library, clicking the ellipsis button to the right of the album will allow you to quickly set the selection as the Primary version.
If the albums haven’t been grouped, group them first, then select your primary version.
Also, toggling primary across versions happens quickly and isn’t always easy to detect. I hope this helps clear up your difficulties.
