the module/card is broken?  this info comes from show diag, not inventory.
the output does look odd, 3 hvers entries for slot 1.  there must be some
daughter entries in the show diag output for the ISE card that rancid is
missing; its hard to get that data because the output formatting is
inconsistent even among platforms with the same IOS rev.  However,
inconsistent o/p is an artifact of what the device is returning, not
rancid.
