At first glance, your issue seems to be a simple relationship error.
Are you sure that the successors to "#1370 Construction Starts" are the activities # 1080, 1070, 1110 ?? Can you display the logic ties on your next screen shots?
Usually, if an activity has no predecessor it will get slammed against the data date after calculating the schedule. Looks like those activities have no valid predecessor (#1370 Construction Starts).
Hope this helps,
