Bad expiry dates with AIR and custom replication periods

Hi all,

I have 2 netbackup appliances running 7.5.04.  One device replicates images to the other using AIR.  I've setup some custom retention periods, though when replicated the image always has a 1 week expiry date on the target appliance, instead of the custom period.

The issue never happens on the source appliance, wether custom or standard the expiry date its always correct.  The destination appliance works fine when using AIR with standard retention periods.  The custom periods are setup on both appliances

Outputs are attached for a testing job.  It should expire on the destination device after 1 hour

any help is appreciated :-)
