metadata is not taken from cr2 file

I add metadata via Bridge (e.g. description/keywords) to a CR2 file, resync the folder into Lightroom, so that metadata should also be inserted into Lightroom. Now when I write new files from Lightroom, the metadata is not sent along.

I would also use the Bridge Photoshop image processor, but it doesn't offer the option to resize the image by specifying, for example, only the long side.
