Custom Netflow Sensor - Why do my Channel definitions fail to register

I have a custom netflow sensor using 10 channels. The details are as follows:

#1:VOIP-IN
DestinationIP[10.7.48.0/24]

#2:VOIP-OUT
SourceIP[10.7.48.0/24]

#3:SANDBOX-IN
DestinationIP[10.7.49.0/24]

#4:SANDBOX-OUT
SourceIP[10.7.49.0/24]

#5:ADMIN-IN
DestinationIP[10.7.42.0/23]

#6:ADMIN-OUT
SourceIP[10.7.42.0/23]

#7:PREPRESS-IN
DestinationIP[10.7.46.0/23]

#8:PREPRESS-OUT
SourceIP[10.7.46.0/23]

#9:SERVERS-IN
DestinationIP[10.7.40.0/23]

#10:SERVERS-OUT
SourceIP[10.7.40.0/23]

When I use this channel definition configuration, only Channels 5-10 show up in the channels and overview tabs. Channels 1-4 are all /24 subnets but from what I gather, this should work. PRTG shows no error when adding this configuration. I have also tried using SourceIP[10.7.48.*] with no luck either.

What do I need to change such that all of the above config will show up in the Channels tab, and subsequently on graphs?

Dear Jonas,

the channels do not appear, unless PRTG has detected traffic that matched the pattern. So, if you would wait a longer time (and then sometime traffic would flow that matches a definition) the other channels should also appear.
Please also bear in mind, that once a traffic was "put" into a certain channel it cannot be accounted for another channel as well.

Best Regards.
