Get Business Days Between Dates for Location Step Returns Incorrect Count in Decisions

I’m using the 'Get Business Days Between Dates for Location' step in Decisions to calculate the number of business days between two dates, but the results don’t seem accurate. Even when there are no holidays or only one holiday, the count is off by a day. Adjusting the "Include Start/End in Count" option doesn’t resolve the issue. Has anyone else experienced this or know what settings might affect the calculation?
