Extra Easy Wholemeal Pitta Bread

I'm really annoyed as just bought some wholemeal pitta bread from Sainsbury's as thought I could use it as a HEXB. However I've just checked online and it doesn't count as HEXB and is 7 syns! Only Co-op and Tesco pitta bread count. Does anyone know why that is? :sigh:

TBH, I thought it was Asda & Co-Op only.

It's to do with the ingredients I believe - most have oil content.

and to do with fibre content..
