In trying to deleteĀ  some null connections in Spectrum One Click, It says "you do not have permission to delete the following connections: null->null null->null null->null null->null .
Spectrum 10 - all versions
This could be due to a corrupt neighbors list
1. Put the view in edit mode

2. Cut all the models from the view, and paste them back in

3. Save the view

This should rebuild the attributes in Spectrum One Click
