On a 10Micron mount, when entering a Longitude value in 'Site Management' the driver updates the mount coordinates but skips the seconds (ss) value.
For example, entering '02:38:30' in Ekos, will results in 'E002 39 00' on the 10micron handpad.

For Latitude the behavior is different: seconds are stored correctly.
Looking at the log, the reason seems to be different decimal places for Long (5) and Lat (only 2) when setting the Observer location.
