Question about 1095-A (healthcare) and filing jointly

I got married this year and I am filing jointly with my wife. 

I had a health plan through healthcare.gov last year. Based on my projected income for 2019, I was give roughly a total of $500 in credit last year.

 

My income was about what I projected, however, when I input my 1095-A, my refund goes down about $500 (it removes all benefits I received in 2019)

 

Is this somehow also taking my wife's income into account and basically saying I made too much to receive that credit? Or could I be doing something else wrong? Do we have to file separately for me to get the 1095-A benefit?

 

Thank you for any help.
