Claim Digger Apparent Error

 I ran claim digger on a project to see what changes were made between the current and previous versions.  I found hundreds upon hundreds of changes,  most of which made no sense.

As a test,  I copied a project and ran claim digger on the original and the copied project.  I would have expected there to be no changes in the project.  

Instead,  I got pages and pages of changes including changes in Relationships, Added WBS's, Deleted WBS's, and changes in relationship lags.

I have enclosed the Claim Digger Report for your reference.

Is there a glitch or some sort of update I need to install to correct this ?
