Bug in my model referenceing two different date tables

Hi, I have been trying to use one date table with two different dates, and found some solutions on here which is great - thanks! However, it still isn't working for me, even though it looks like it should. Hopefully someone can spot what I am doing wrong, whether in model set up or DAX. I canot upload the PBIX for privacy reasons....

Snip of affected tables;

Linking on Quote DateKey (Integer) = Reporting Date DateKey (Integer) (Active 1:1 Cross filter Both)

and

Linking on Sale Completed DateKey (Integer) = Reporting Date DateKey (Integer) (InActive 1:1 Cross filter Both) - cannot make active due to circular reference.

Also Linking on Quote DateKey = Policy Information Quote DateKey (Active 1:Many Cross Filter Both)

and

Linking on Sale Completed DateKey = Policy Information Sale DateKey (Active 1:Many Cross Filter Both)

(I also tried with the date field, same results)

 Quote DAX - Seems to work:

Quote Policies # = Calculate(
SUMX('Policy Information', 'Policy Information'[Quotes Started]),
Filter (Values ( 'Quote Date'[DateKey] ), 'Quote Date'[DateKey] >= Min ( 'Reporting Date'[DateKey] ) ),
Filter (Values ( 'Quote Date'[DateKey]), 'Quote Date'[DateKey] <= MAX (  'Reporting Date'[DateKey] ) ))

Sales DAX - Not Working:

Sales Policies # = Calculate(
SUMX('Policy Information', 'Policy Information'[Policies Sold]),
Filter (All ( 'Sale Completed Date'[DateKey] ), 'Sale Completed Date'[DateKey] >= Min ( 'Reporting Date'[DateKey] ) ),
Filter (All ( 'Sale Completed Date'[DateKey]), 'Sale Completed Date'[DateKey] <= MAX (  'Reporting Date'[DateKey] ) ))

I expect to see 199 Quotes and 93 sales but instead I see:

 Please help, and let me know if I can provide any other information to help solve this conundrum...thanks!
