Messed Configuration Matrix table shows duplicate entries and does not shows some of the configurations that were actually run. This renders this feature virtually useless.

On attached image table shows that it wasnt run on ingot but was run on pintov1 and superforg1 for both hpux and for linux and even did this twice for the superfrog1. Same time both columns hpux and linux contain the same links on corresponding row:
/lastSuccessfulBuild/label=pintov1,os=linux,req=tws/
/lastSuccessfulBuild/label=superfrog1,os=linux,req=tws/
For the superforg1 there are 4 identical links provided above.

Same time in build log we can see the real configuration that were run:
Triggering pintov1,linux,tws: /label=pintov1,os=linux,req=tws/
Triggering gdrci,hpux,tws: /label=gdrci,os=hpux,req=tws/
Triggering ingot,hpux,tws: /label=ingot,os=hpux,req=tws/
Triggering superfrog1,linux,tws: /label=superfrog1,os=linux,req=tws/

gdrci is missing in table completely and for ingot it shows that configuration was not run while log states that it was:
pintov1,linux,tws is still in the queue: Waiting for next available executor on pintov1
pintov1,linux,tws completed with result SUCCESS
gdrci,hpux,tws is still in the queue: Waiting for next available executor on gdrci
gdrci,hpux,tws completed with result SUCCESS
ingot,hpux,tws completed with result SUCCESS
superfrog1,linux,tws completed with result SUCCESS

I dont know if it matters or not but there is suspicious entry in the parent build log:
Interrupting #19
ln -s builds/.../builds/../lastSuccessful failed: -1
ln -s builds/.../lastStable failed: -1
TEMIP-CA-cleanup #1522 is already in the queue
Finished: SUCCESS

#19 links to /label=gdrci,os=hpux,req=tws/19/console that states that this build is finished to the end with success:
