Relationship Cardinality - Many to one (*:1) issue

‎08-24-2022 12:21 PM

I have a dimtable with a distinct key column. When I try to create a relationship with my fact table, pbi desktop forces a many-to-many relationship. I have validatd via powerquery that the key column is 100% distinct, so I have no idea what is going on here. 

 

Any ideas?

I have had issues in the past with trailing spaces on my data causing this issue. 
For example Power Query considers "cellContents" and "cellContents " as distinct where Power BI considers them a duplicate value.
