QSFP split-port only first lane is useable 6.2.4-to-6.2.6

I have an 1100E with 2x QSFP ports. I enter the command

set split-port "port33" "port34"

The system reboots and I see my 8 new ports. The problem is that the distant end only sees traffic on the first port and the fortigate downstream switches show all ports as green. I enabled LLDP on all of the ports and I can see neighbors on 33/1 and 34/1 but no traffic on all of the other ports.
