This issue has plagued the DJ 1701-G since its release.
I have found that if I separate the first time around then re-integration works fine but... If I decide to separate a second time, the problem that you are facing rears its ugly head. So... I've decided just to separate/re-integrate just once and live with it.
In a nutshell, it's a bug in MVAM that as far as I know, no one has ever solved.
