Measures won't filter by related date table

[HPoyzer]

Hi, I'm pretty new to PowerBI so I could be missing something obvious but I have a Calendar table (named DimDate) and a Work Orders table that is has a 1 directional One to Many relationship (I've checked that both fields have the same date formatting and they do unless I'm missing something). For some reason, the measures relating to the Work Orders (such as the type of work being done) won't filter by the dates/months from the DimDate table. I've tried everything I can think of and find online but nothing works so I figured I'd come here and post my own situation. 

For reference, I have the exact same relationships to the finances table and have 0 issues there so I'm really unsure what the issue could be.

Relationship between DimDate and WorkOrders:

DimDate table:

Related date field in WorkOrders table

Example visual showing that 41k rows of data aren't being sorted by the date. The date field in this table is the Date field in DimDate table.

Sorry if this is a silly question, I've spent all day stuck on this. Thanks (:

Nevermind, I finally fixed it. I was certain the formats were just date but after converting them to number I could see they weren't so they've since been converted and updated.
