Planned TSS: generic plan VS actual plan

If I consult a full training plan (for example, OLIMPIC TRIATHLON SPECIFIC PHASE, HIGH VOLUME), I see every week has a target TSS.
When I set the plan into my calendar, weekly target TSS are different (both as a value and as a trend).
This is not clear to me.
Is there an explanation?

We definitely need another TSS line in the calendar (for planned TSS - i.e. from the original training plan - not amended/planned) to provide some reference as to where you should be in relationship to the original plan.
