Data sharing issue

I am having an issue with transferring my data. I have a few photos which I hope can illustrate the issue. Some of my pages aren’t working due to data from other pages not connecting. the issue is. the linked buttons, icons, and lists all state that the information is being transferred, but when I check the page I want the information transferred to I don’t get anything back. It is also asking for data information from pages that aren’t linked, and do not have the data information. Anyone have anu ideas on how I can tackle this?
