Try purging your camera raw cache. You can do this in Preferences->File handling. I've been running into this same problem since the last update to LR.
Hi Jao - thanks for the suggestion, but doesn't make any difference - still doesn't update the image. May have to contact Adobe next week as this is affecting my workflow pretty badly now.
You are right. In the Library module the image looks like it does in PS. Once I switch to the Develop module it changes, but not all the way back to the original.
Updating the Metadata does nothing in the develop module.
But when exporting that image from the Library module or Right clicking in the Develop module and selected Export I get the updated version.
It has something to do with the Preview Cache. I deleted all the files and folders in the Previews Cache folder and now it displays correctly. The original Preview isn't being updated. I suppose once a preview is created LR is having a hard time updating it.
Hope you get some help from Adobe. Keep use posted.
