Yes, somewhere between 2.13.1 and 2.14.7 it broke.

The patch (against 2.14.7) to correct this behavior  is:
[root at ldap bin]# diff -u cfgmaker /usr/bin/cfgmaker

This patch will be included in the next version of MRTG.

There have been several reports on this list.  I only recently upgraded
from one of my custom-hacked versions to see what was in the release
version.
