5DMkIII + GP-E2 + DPP

Trying to find somebody with 5DMkIII + GP-E2 combination and uses DPP to process RAW file to say Tiff 16 bit

To explain, I Geo Tag nearly all my images using GP-E2 on my Mk III, I do some processing with DPP and finish off in PS CS6 when converting from RAW to 16 bit Tiff only certain files transfer the GPS coordinates, all I have come up with so far is that it seems related to certain lenses, for example my 70 - 200 converts fine but converting files shot with my 50 and or 24-105 loose the GPS coordinates on transfer.

Can anybody confirm this or offer an explanation? DPP is latest version.
