What is wrong with my structure?

Hi there

I have a data structure consisting of a fact table and i've joined a general date dimension to that table via a full date.

I'm using import as the query method. 

I've used this structure heaps of times and was working on a similar structure earlier today, but when i created a new structure - my data is no longer returning properly. 

The dimension table results are not joining to the submitted date as expected and i only have a handful of date dimension results that are actually joining to the fact table. 

My date table is populated. Earliest date and Latest date are returning as below screenshot. 
Where have i gone wrong??

I've checked data times are "dates" for the join. 

and i've tried refreshing the source.
