Unable to update workflow with a new dataset

For my first task, I was counting repeats on exons on human chromosome 22 by importing data from UCSC main and using various tools. Now I am trying to create a new workflow with the previous history by trying to update repeats datasets with CpG Islands. When I am executing the work both the imported data sets (Knowngene on Chr 22 and CpG Islands) do not show up. Only the manipulation that I did with tools shows up. Please see the picture attached.
