The bug is real but it's not exactly well described.

What YifanHU multilevel algorithm does is that it groups nodes in clusters to fasten layouting. As a result new meta-nodes are created during the process. These meta-nodes don't have any attributes and have default size 1 (tiny). When the algorithm finish it ungroups these meta-nodes and therefore meta-nodes are deleted.

With you dataset it appears that Yifan-Hu Multilevel doesn't finish well and leave meta-nodes. You can see that they remains by clicking on "Hierarchy". Instead of a unique Level, you have two levels.

I'll rename the bug accordingly.

I'm pretty sure that the problem comes from self loops. The bug contains two issues:

• meta nodes not removed
• edges between normal nodes are missing

I fixed the second point in rev 2071.

Two years and still open while labeled High?!

Won't fix as the hierarchical graphs are being deprecated in the next version
