Issue connecting two columns from a uploaded dataset to the same target vertex in GraphStudio

I am struggling to connect two columns from a file I uploaded in the Map Data to Graph interface to the same target vertex of an edge. When I go to draw the connections after mapping my .csv to the appropriate edge, GraphStudio won’t allow me to connect the two columns of data to the same target vertex. Is there a way to bypass this? My end goal is to go to Explore Graph and see the two data points associated with that target vertex’s associated node.

Not sure if the image will upload after I submit this, but basically I want to also connect column “C” with the target vertex “y” as well. But when I try to do that now, the current connection from column “B” to the target vertex is cleared.

Any clarity on what I am doing wrong would be much appreciated!
