Visuals Displaying Negative Values as Zero

I have a measure which takes the difference of two measures (column 3 = column 2 - column1 in the image below) to show change over time. However, in multiple types of visuals (ex., card, matrix), all negative values render as zero. The grand total in a matrix also shows zero, which is only possible if some values from the expression are negative because the total of all values must be zero for this particular measure, so I know the issue relates to rendering negative values rather than not calculating negative values. Does anyone know why this might occur?
