as I said in my previous post, there is no connection between this list of 7 years and your DistinctCaptureDate.
We created a synthetic dimension, but no link to your data model.
If you want to filter your data for years, you can add a year field to your data model and filter this for say the last seven years (if you want to display all this seven years without having actual data, you can additionally add a calendar table to your data model). I posted a proposal for this to another of your postings yesterday.
It's pretty hard to tell what is the right solution for your needs, maybe you can tell us the business need or learning exercise detail description 😉
