Hi there! 

So i have created a report based on a form that also has a subform in it. They are related with a bidirectional relationship. 

The problem is that in the report (where i have 1 column from the form and 1 column from the subform), filtering options doesn't work when applied to the subform's column. 

If you see the attached image you will understand better what i'm traying to acomplish. In that picture there is a filter aplied to show only records from the last month (date is from subform). But as you can see it doesn't filter properly.

Any ideas on how to accomplish this?
