Chopped traffic graphs on miktrotik switchOs

Hi guys ,
Monitoring my switchOS device , created graphs are not ok , take a look:
This is what I can set on switch snmp menú:


and this is what Im getting on librenms
snmp_switchos2
As you can see , outgoing traffic that is bellow 115Mbps is ok , problem is with incoming traffic.
Is there any think to change /check?

Regards.
Leandro.

What version of switchos do you run? using snmp v2 version?
