Captioning is suddenly clipped on publish but looks OK in editor/preview. This is for 2 lines – looks OK with one.

Hi Nathan,
The captioning box size is set based on the initial size you see when the editor loads.  So, my guess is the first line you see is only a single line of captions, but you have other captions that are double lined.  Increase the height of that box so it fits 2 lines and you will be set.
Let me know if you have any questions.
