LIghtroom and Bridge Keywords don't match

Question

I use PhotoMechanic (with the stationary pad setup) to ingest NEF images, then convert them DNG with DNG Converter. I add keywords using PhotoMechanic, Bridge and Expression media and Edit using PS to create web versions.
I'm trying to use LR 1.3 and starting to import them all.
When I look at the keywords in LR 1.3 the DNG are all the same, however the JPG in LR 1.3 are different from the other three (PhotoMechanic, Bridge, Expression Media). I've read metadata from the files in LR 1.3 and there is no change to the jpg.
It looks like LR 1.3 does not extract metadata from JPG the same way as Bridge does.
Any ideas why?

There are a lot of profiles for Raw-images but much less for JPG images.
Lr will display only those lens profiles that apply for the file format in question. So when you have a JPG image the profiles for Raw images will not be displayed in Lr, and vice versa.
If you don't have the correct lens profile in you list you have to download it.
For this you need the Adobe Lens Profile Downloader.
And for this program you need Adobe Air.
Download both programs from Adobe's website - they are free of charge.
Then install Adobe Air first, and when that is installed, install the Lens Profile Downloader.
Once it is installed just open it, it is self-explanatory and will display all available lens profiles once you have selected your camera and lens makes.
