Cisco 9500 showing additonal ports after upgrade

[cae_technology]

Cisco C9500-24Q upgrading stack from 16.6.04 to 16.12.04. The upgrades have been a success – everything is working fine, however following the upgrade I have acquired 192 tengiga ports in the interface list that weren’t there before (96 on each switch). I’m sure this is a cosmetic thing – I don’t have anything plugged in which would add 96 extra ports per switch, and the 24 ports I expect are still there and functioning. Reviewed current bugs anyone has seen this before?

Those are "place holder" ports. 

Some of the ports of the 24Q are multi-personality:  24 x 40 Gbps ports or 96 x 10 Gbps ports.

Thank you Leo, so its not a cosmetic issue but expected. However, this has never shown before is it an enhancement feature?

It appears to be so. It seems like the new IOS breaks down the 40Gig ports to multiple 10Gigs (24x4=96) without needing to do it manually.
