Product Block

I’ve been having trouble doing some actions I know are possible while editing my site. I’m thinking it might be because I’m building it on an iPad Pro? I added product blocks to my homepage and wanted each one to be a different item. When I go to select the item it doesn’t show all of them and so there are a few repeats. Does anyone know why this might be happening? How do I solve this problem? Does anyone else experience issues when they edit their site on an iPad? There are a few other things that happen that make it very frustrating and time consuming.
