Not sure,
Haven't seen those options. Sounds like an older DM version. I use 4.6. Hopefully someone else will have an idea.
These are my two screens. The first one is at startup and I select Syncronize. The second one you want select the syncronization label on the left and set your parametrs. Once they are set you can select the synconize button in the center of the second screen.
Sorry about having no other ideas.
