Elevation readings are not what I expected

recently purchased catalyst, with one month precision, what am i missing in regard elevation values its measuring, seems to be that they are not OSGB36, on a known point there seems to be a difference linked to the local ellipsoid and the global ellipsoid (im no expert), ie, I know the elevation is 39m but I get a measure of 90m, what am I missing here, position is brilliant just elevation, but elevation is consistently precise
