When I read in an Exodus II file with three polygonal blocks named POLYGON\_BLOCK\_1, POLYGON\_BLOCK\_2 and POLYGON\_BLOCK\_3, Paraview (5.5.2) shows me POLYGON\_BLOCK\_1, POLYGON\_BLOCK\_1, POLYGON\_BLOCK\_2 in the Blocks list (Note the repeated POLYGON\_BLOCK\_1 and the absence of POLYGON\_BLOCK\_3). I verified the input by using ncdump on the Exodus II files. I am not sure how to attach a file to this post but I believe it should be reproducible with any Exodus file which has multiple polygonal blocks
