We got same problem, one of the upgraded MP1 platform our customers: but with the "Software Management Upgrade" package/policy.
No way, no repair was working. And Symantec support told us all existing package/component will disappear if we remove and reinstall the software manage solution (and not sure will work better than the repair)
Also not possible to export packages/components, (export possible, not import) for restoring them after removing the "soft manage solution" for a reinstall.
:(
Why repairs are not able to solve this kind of problem ? Looks like a bug, a big one.
