Did you get that from a API or a straight GPX because here is what Clyde has to say about that
Clyde from previously noted topic
It is a little more complicated that that.
Only the api give us true corrected coordinates in the sense that we can now distinguish that the coordinates are corrected, and we have the original.
PQ and single GPX download give us the corrected coordinates but there is no way of knowing they have been corrected so GSAK can't distinguish them from the original and we show them as the original coordinates.
