[mrtg] MRTG bug?

Hello,
I am trying to read several parameters of about 20 DOCSIS cable modems. MRTG is not saving the TX Power correctly of a couple of the cable modems. The problem is that MRTG will read the correct values and then write it to the log file *always on the first line*. This means the first line always contains the latest reading and the rest of the file only has zeros.

Is this some configuration error or an MRTG bug? Below is the debug file, the configuration file and the log file.

Thanks a lot,

Nuno
