Incites copublication network - self edges

[risserlin]

A lot of the authors in copublication network built from incites file have self edges (the file lists the same authors multiple times).
When I try to delete the self edges by selecting it and going to Edit-delete selected nodes and edges the self edges get deleted but so do all the edges of the node the self edge is connected to.

Not sure if this is an issue with the App or cytoscape.
