I hope you are well today and thank you for your questions.
I have portfolio projects with images and I wrote captions in media library as you can see in attached files:
with default layout the caption is shown wrong,
It is not wrong, actually it displays text from Title field of image as shown in the attached screenshot.
in gallery layout is not shown at all.
there is a way to have correct captions in gallery layout?
Currently the theme doesn’t support it but we will add this feature in the future version of theme.
