New UI: advanced options do not work

Using 2.4.7 of wp-flickr-press with the old UI and some extra options configured within the advanced options area:

Flickr information is all entered correctly using the old UI, but when trying the new UI from Add Media the [description] element is improperly added (only the first part of the HTML is shown).

I understand from a previous issue that this is not currently planned to be implemented within the new UI, but it is an important part of my use case for this plugin.

Thanks for the responses so far
