My understanding is that different software calculated medians in ways that leads to different answers (for example excel and SAS).

Our median function just sorts the data and picks the middle value (I forget how it works when there are an even number of values).

Until two months ago we had MS Server 2008. I will have to try the new function since we moved to 2014 (I had hoped we would move to 2016 to get R, but we have a policy against getting a product less than a year old because of possible bugs).

Its an IT policy not mine...
