LLDP Problem with Netgear ProSafe GS752TPv2

I have about 15 Netgear switches here. All show - if an LLDP-capable device is connected, this in the “Neighbours” tab. Only one Netgear ProSafe GS752TPv2 switch did not show any neighbors, although another LLDP-capable switch is connected to it. (Which in turn correctly displays Neighbors) All other SNMP data are probably correct. Can I do something there?
