AMSL Alt NOT found in geo-ref tool

Hi, I'm having an issue trying to geo-ref my images.

I'm using the dataflash log, and for each photo get the message: "Photo DSC09916 processed from CAM Msg with 0 ms shutter lag. AMSL Alt NOT found" 

If I uncheck AMSL alt and have a rel. alt base of 0 , it lets me georef the images. When I click 'location KML' then bring up the properties of one of the tagged images in google earth, it displays the AMSL alt correctly there, but when I click the 'geotag images' button, and look in the EXIF for each image, it has only been tagged with the rel. alt.

If I change the rel alt base to 220, and run the geotag process, the images still only come through as if they had been tagged with a rel alt of 0.

This is on MP and it did it also on MP Copter is running 3.3-rc12.
