Your affordance for sources is misleading and confusing. When I am viewing a dataset post schema creation then this link affordance makes me think that it's related to the number of results found in a cell where multiple results are expected. But when I'm adjusting the research plan, I do care about the sources. Suggestion is to introduce a "Review Mode" where the link affordance corresponds to data source, else it refers to number of links per cell. This will solve your problem and make it be less confusing. Currently, this as well as many other things make me just want to download to csv and edit in google sheets. it's too frustrating to work with.
