NFSen not showing on device

Hi folks,

I have installed and configure an NFSen server on another machine. I followed all the steps on docs https://docs.librenms.org/Extensions/NFSen/ and configured a NetFlow on cisco switch WS-C3650-48PD but I don`t see any NFSen tab on this device. NFSen server is working correctly. I added some other device on that server and I can see all the graphics generated. Please what can I do to enable this option in librenms server.

Best,

Andi
