In nProbe —json-labels seems to be working with the default template, but not with custom ones

We're sending data from nprobe in collector mode to an ELK node.

When we're using standard templates in conjunction with --json-labels, not using -T parameter, everything works fine. Data is received and seen ok on ELK.

If we use a custom template with -T, and not using --json-labels, we receive all the info in ELK but we don't see the field names, just the IDs.

If we send custom templates, -T parameter, in conjuction with --json-labels data is not seen in ELK. It seems that custom templates with --json-labels have some weird behaviour. I must say that data seems to be sent to ELK because we can see traffic flowing through the FW from nProbe to ELK.

Our nprobe config is :

Version: 10.4.240307
Build OS: Ubuntu 22.04.3 LTS
Edition: nProbe Enterprise L

Thanks
