Titles and Captions missing on move to new PC

another idea to check:

do you have several images highlighted together? If so, depending on the (newish) display mode button clicked for the Metadata panel LrC will either present the metadata for just the active image, or else summarise the metadata across all highlighted images. In the latter case, when the highlighted images have got differing info for certain metadata fields, IIRC those fields may show blank. This setting should of course not apply when you have only one image highlighted.

Could it be that the Metadata panel is in Edit only mode?

If so, click the icon in the top left corner to get back to View and edit mode.

Hi

My old desktop PC has died on me so I have bought a new one and moved the storage hard drives from it to an external hub.

I have copied the Catalogue file from its place on one of those hard drives to my new PC and then installed Lightroom. It easily found all the photos and everything seems fine, except none of the Titles and captions are showing, which is pretty disastrous!  The strange thing is that as far as I can tell all the necessary words are listed in the Keywords list. If I click on one of the words in the list it finds photos of that item.

I am totally stuck, any ideas please?

Just to make sure I am completely understanding what you did ... I ask the following question ... did you import the photos into the Lightroom Classic catalog on the new computer? (It doesn't sound like you did that, but I ask just to be 100% sure)

Are these images in LrC Library module showing a metadata mismatch/conflict?
