[Xymon] NOPROPYELLOW ignored for one test

I'm having problems with NOPROPYELLOW but only for one test. It seems to completely ignore just that one.

Factors:

• NOPROPYELLOW is successfully being applied to other tests.
• There is no change when this is the only NOPROPYELLOW host or one of many.
• There is no change if I use NOPROPYELLOW:+mycustomtest or NOPROPYELLOW:mycustomtest.
• I am not using --nopropyellow option to xymongen.
• It fails when used on the .default. or the specific host line (or both).
• This test is run on one host which reports on behalf of many others.
• I've verified that the test name is correct using xymondboard. sudo -u xymon xymoncmd xymon localhost "xymondboard test=mycustomtest"

Any suggestions for my next step in debugging? Dave
