Option to hide the image description?

Greeting, thanks for this great plugin!

Is there an option or any way to NOT show the desciption of the image and show only the caption? All of my files have the same value in all 4 fields (title, caption, alt text, description), so I will have to modify them through the gallery in order for this to work. Showing exactly the same text in two different lines when someone clicks on an image, looks like a bug. Maybe an option that could be included in a future update.

Thank you in advance.
