Don't get why you're confused, you gave the distinction yourself:

A) Aircraft call sign \ type
B) Departure point & destination
C) Present position
D) Level
E) Additional details / Intention
and
Quote:
Position reports shall contain the following elements of information:
A) Aircraft identification
B) Position
C) Time
D) Level
E) Next position and ETA
See?
It's not exactly crystal clear given that it is asking for "Present Position", i.e. not "Previous Position" or "Position in 5 mins", but "Presen PositioN" which it then defines how to make a "Position Report" in the next paragraph. Hence it is still confusing to the beginner....
