Help with a SQL comparison Query

I have the following two queries below. What I am attempting to do is compare my results from current production to archived data from the week prior. My goal is to compare sales by season OTSWIP and SUM of the std_cost. However when I attempt to join the two queries together my results get exaggerated. I'm not certain what I am doing wrong?

Production Query is as follows. I Receive 23 rows. Results are attached.

When I attempt to join these either in a left Join or Right Join my results get exaggerated? I know this is simple however I am struggling to grasp what is wrong.

What I'm looking to do is determine the difference between OTSWIP this week from last and the percentage change between last week and this week in dollars.
