Do we have to add all the content ( paragraphs , demo texts ) in main psd template file we submit ? Or that all is just to display in preview ?

I have submitted my PSD file which is soft rejected . They gave me some reasons on which i am working right now. I am a beginner , I want to know does we have to include all texts , paragraphs and demo text in main file( files for sale ) that we have displayed in preview or that is just to display in preview.
