Your issue is that you use chart expressions without aggregations, which will not work in most cases:

Use Aggregation Functions!‌

If you want to group by NameProduct, you will need to decide how you want to aggregate the dates, e.g.

=min(StartDateWO) instead of =StartDateWO (or max(), or avg() etc. can't tell without knowing your full requirements).
