Problem With Traffic Analysis

I am using a EdgeRouter  X  running firmware version 1.8.5.   When I examine the “Traffic Analysis” window on the right hand side which shows “Top Apps (Tx Bytes/Rx Bytes)”, there is traffic being shown crossing between the WAN side (eth0) and the LAN side (eth1) for

‘application cat_id="137" app_id="61" name="DNS"’

but traffic is not being shown for

‘application cat_id="137" app_id="4" name="IGMP"’

and

‘application cat_id="137" app_id="118" name="ICMP"’

when I know such traffic is crossing between those two interfaces.  

I am at a loss as to why this is happening since the traffic application category is the same in all three cases (137).  You would think if “DNS” traffic is being shown the others would be shown as well.

Simply put, what do I have to do to see  “ICMP” and “IGMP” traffic as separate items and not have them grouped with unspecified traffic and shown as “Other” or “Web  -  Other” as they are currently?
