Most important seems that when you send your experience letter you did not list out duties properly for your NOC Code. that is why they went to look for your qualifications and all. No need to worry though: Get an experience letter from employer listing duties for your NOC code: 2283.
I just created a sample for you, feel free to add / remove any duties u want to :
