Enabling / disabling a source or provider causes a new version each time but is not displayed when comparing versions

Steps to reproduce:

1. Create a source or provider
2. Enable, then disable that source or provider
3. Click in to the source or provider and display version history
4. Choose any 2 or all three versions, click compare

Expected result: ??? should enabled status show up in versions?
Actual result: all selected provider / resolver versions show up with no apparent changes
