CRS317-1G-16S+RM SWOS 2.8 Issue with SFP+ ports

We have multiple CRS317 deployed and always had trouble setting up LACP to connect with our CCR1072. which seemed to be a issue with SWOS 2.7 and below not allowing traffic to be balanced properly.

We recently tried to update one of the CRS317 unit to SWOS 2.8 and realize that some SFP+ ports become unusable. on one occasion, Ports 4, 8, 12, 16 become unusable. Any comments?

Reason i am using SWOS is because simplified setup for ingress limit control and mac based bandwidth control. less issue with VLAN.
