Missing lines on line chart but legend shows all.

Hi there, I've been battling this one for over a week and am about to lose my mind. Charts are my one major excel kryptonite. They rarely do what I want and I don't understand why. I've even taken a class on it but when I get to real world data it still often goes sideways.

I wanted to create a chart to show total $ of adjustments by category (reason for adjustment) with months as the X axis. I created a line chart and I can see all three of my categories in the legend, but only one of the lines shows up on the chart itself.

I've been playing around in chart settings but have had no luck. Can anyone see where exactly I've gone wrong? This particular problem happens to me often. Would love to learn. Thanks so much!

Hoping my attachment comes through on this post.
