cd-existing-object error after enabling AD recycle bin

I am using MIM 2010 to sync my Development AD domain with Production Domain. Recently I had deleted some core MIM groups and users in Dev because of which I reverted the VMware snapshot of my DC. After that I enabled recycle bin in my DC.

Now when I execute the whole refresh process which include the following steps:

1. ProdMA Delta Import

2.DevMA Delta Import

3. ProdMA Delta Sync

4. DevMA Delta Sync

5. DevMA Export

6. DevMA Delta Import

I get completed-transient-objects status when I run the profiles DevMA Delta Import and DevMA Delta Sync.

In DevMA Export I get the error cd-existing-objects error.

Any ideas?
