Automatic zone detection not detecting boundaries manual zone boundary gives wrong door number

[Niranjan Das Sharma]

I was trying to define zone and extract door window numbers and other data. 

I was getting wrong numbers when i use manual polygon zone method. 

automatic is not detecting boundaries. 

 this is the screen shot of original space to mark zone. which was failing to detect 

 This is a simplified version of same space reatining only the wall and removing all doors, windows beams and everyting else. Its still not detecting. where could be the possible leak? Pleas help

Ahh yes, it seems it also needs to belong to the same design option.
