i fooloshly checked the GPS box on a preset which means I have imported a bunch of images and the GPS metastatic is now blank ( even though the GPS info is in the original image and the DNG)
is there an easy way to rejmport kl just the GPS data? The refresh metadata didn't seem to bring in the GPS values

Hmm, it sounds like you may have done Metadata > Save Metadata To File or have set the option Catalog Settings > Metadata > Automatically Write Changes Into XMP. In that case, after the import preset cleared the GPS fields, LR then overwrite those fields in the files with blank values, permanently losing the data.
To verify this, upload one of the pics to Dropbox (or similar) and post the link here, and we'll take a look.
