Having problems importing bip files into bip files...

[itsterril]

When i import bip files (that came from proE for multiple concept compairison), i have noticed that in the scene tree, each item has the same name. Didn't think this was an issue until i save the file, close it, then open it back up. Upon reopening it, all that showes up is the first bip import file. there are more there, but they all are the same file as the first. Not sure what is going on here!

Any ideas?
