I don't know why HP can't get the date right. <Enter facetious comment here>
They can get it right directly via version control, but can't seem to get the version control and HPSim to match.
I'm at the same HPSim and VCRM as you, and already at 2014-09 SPP. Same results. The ILO ROM version doesn't match either. This occurs on G7 and Gen8's as well. My Gen9's will be arriving shortly and I suspect the same.
I still have to copy and create a custom baseline and remove the System ROMs and ILO ROMs from reporting.
