I am attempts to add blocks to my individual product pages. I want to be able to vary my blocks, depending on the product. What I find happens when I try to do this, is that if I used a block in a certain place, the program will copy that element onto the product pages of the other products that I didn't add it to. It works the same with deleting things I do not want, they also get deleted on pages where I did not want them deleted. Other times the content on the slides, which I wanted to vary between product pages, gets overwritten on pages I already edited, taking whatever new content I type, and replacing all my old work with that. 

Maybe this is part of how the program works, and I will have to rethink my design strategy. I would prefer however to be able to use various blocks, or have the same block with different content on different product pages. I was thinking maybe there is a setting somewhere that I need to change.

Is anyone having a similar issue, or know how to resolve such an issue?
