Trouble Generating Static Captions for Images in InDesign

[m5heath]

I want to generate static captions for images in a document. I want to do it this way because there many images. I have watched various tutorials online and I think I've done it correctly. First I opened an image in Bridge, opened the metadata tab and in the field called 'Description' I entered the text of a caption. Then I placed the image in InDesign and set the text wrap. Then I went into Links panel->right-click image->Captions->Caption setup and in the dialogue set the Metadata dropdown to 'Description'. I entered a para style, set the alignment to 'Below Image' and the Offset to 6mm. I checked 'Group Caption with Image'. Then I went back to the links panel image, right-clicked and chose 'Generate Static Captions'. The bounding box then duly extended to accommodate a caption but the caption did not appear. Of course I have checked and re-checked everything but I cannot spot the error.

Can anyone shed any light?

Many thanks David for taking the time and trouble to sort me out. You are very kind and it is clear that Indesign is an open book to you.
