The action plan in the objectives module uses quarterly week numbers that start at 1 for every quarter. Nobody, in the whole world, ever uses these kind of quarterly numbering, and you cannot expect your users to manually calculate the weeks for each task.
Please number the weeks as in every calendar from 1 to 52, i.e., the weeks in Q2 should start at 13, the weeks in Q3 at 26, and son on.
Thank you for correcting this mistake.
