IGMP on vlan1

Hello - I have a one switch network, trrying to get IGMP multicast working.  I have followed the manual tyo setup the switch and the device is not fowarding the multicast packets, and the IGMP tables are empty, what am I doing wrong?  Im on the 6.0.6.3 firmware.

I have a not in use older jgs 516pe factory settings that this works fine, but it floods all ports which i dont want.  I want to be able to use IGMP on the gs752 on some ports in vlan1 and unicast traffic on others in the same vlan1.
