Lightroom :: 4.4 - No GPS Data Is Shown On JPEG Photos?

I cannot see any GPS data on my jpeg photos in Lightroom 4.4 (was the same in 4.3), I add the data on the computor using JOBO photoGPS softwear, lightroom works fine with RAW files GPS data but not that added to jpegs, post capture. I shoot Raw files and jpegs with both a Pentax K-x and a Sigma DP1 then add GPS data recorded at the time with a JOBO GPS unit attached to the hotshoe. 

If I use my new Pentax K-30 with a Pentax GPS unit which adds GPS data in camera, there is no problem, Lightroom shows this, RAW and jpegs.

The JOBO unit software give better additional metadata information, addresses etc than the Pentax unit, though it does take more work to use.This issue effects uploads to flickr as there is no GPS location then shown there.

I use Windows7.
