Error on Sync job after moving ESXi Host(s) from Internal to DMZ

[ChristianMoritz]

Expected Behavior

ive got 6 esxi hosts on my vcenter... (the 2 oldest for dmz, 4 newer nodes for internal)
after deleting the old 2 dmz nodes and switching the 2 next oldest nodes from internal to the dmz ive now got a warnung message every 60seconds on the CLI that the there is a duplicate entry...

Current Behavior
