I'm pretty sure that between 8.0.1 and 8.0.17 there are a couple of
bugfixes 
related to duplicate rows with pk scenarios, you should probably take some 
time to upgrade before you spend too much time digging into this (make sure 
to read all of the release notes for those versions in between, i'm also 
thinking there are some special instructions that might need to be done 
somewhere in there)
