Rollback Oracle Linux Patches

I’m trying to investigate how the rollback of OEL patches works. When I try to launch the “Yum Transaction History” dashboard, I get an error and the dashboard crashhes.

1/19/2017 14:35:41.175[ERROR]  Error evaluating relevance: Singular expression refers to nonexistent object.

1/19/2017 14:35:41.175[ERROR]       relevance: (name of item 0 of it, id of item 0 of it, operating system of item 0 of it,concatenation "," of (ip addresses of item 0 of it as string),concatenation "," of values of result(item 0 of it, bes property "Subnet Address"),value of result (item 0 of it, property 2 of item 1 of it) | "",value of result (item 0 of it, property 3 of item 1 of it) | "False") of (item 0 of it, item 1 of it) of (applicable computers of it, it) of fixlet whose (name of it = "YUM Transaction History") of all bes sites whose (name of it = "Patching Support")

Ive enabled the Yum Transaction History analysis and it is retrieving data. Does this dashboard work for anyone else?
