Line and Column Chart Help

Hello!

I have a line and stacked column chart right now. Ideally the columns are most recent test grades, and the line values are the previous test grades. The align zero setting is selected, but there's some issues still with the visual:

The values still aren't properly aligned. For example, the circled values are both 94/94.4 but there's a large gap between the column and the line. Thanks in advance for any help to fix this issue!
