loading groups of .stl/.vtk only loads first surface
On AevaCMB 2.6.1, windows, when loading a group of stl or vtk files in the file > open menu, only the first group is loaded unless all the segments are explicitly chosen, which seems to defeat the point of listing the files as a group.
See this video for example: loading_stl_group
Here is a sample of two vtk that should be able to be to reproduce this behavior: Output_Surface_grouped.zip
