Thanks for your response.
Why would it be intentional?
It worked very well in the old version, therefore we would be taking a step back with the new version!
The possibility of adding or replacing captions in V5 exists but does not work.
If it was intentional, the same reaction would be with the key words as well, but this is not the case.
I hope a solution can be found rapidly as it would be a shame to have to still use V4.6.9!
