[Xymon] The 'bad' syntax has been deprecated.....

After migrating our old hobbit server to latest version 4.3.18, another error message appeared.

Error output: WARNING: The 'bad' syntax has been deprecated, please convert to 'delayred' and/or 'delayyellow' tags

What I noticed on other pages online, the warning usually includes a <TESTNAME> value, but not at our installation. Seems to be very difficult to debug it. Maybe someone has a hint?

Thanks
