CASE WHEN Formula Not Displaying Correctly

Summary: CASE WHEN STATEMENT shows two different results pending the format export

Content (required): I'm using the following CASE WHEN statement to label a value either "To" or "From

CASE

    WHEN "Transaction Distribution Lines"."Reserve" >= 0 THEN 'To'

    WHEN "Transaction Distribution Lines"."Reserve" <= 0 THEN 'From'

END

When I export the analysis as XLSX

it shows all values as 'To' but if I export the analysis as CSV then it displays the correct output.

Does anyone know why this would be?
