As long as the backups complete it probably doesn't hurt anything.

No, that makes it harder to understand. That means that it should
always be using the same previous full run as the comparison base so it
doesn't make much sense for all files to appear different in the 2nd
incremental but match again it the 3rd.

Tar just uses a timestamp check for incrementals so it doesn't actually
compare anything against previous runs.

But only for you - I don't think anyone else has seen this happen.
Maybe Deltacopy has a bug.
