Photo titles in lightbox gallery

Question is where did you fill the title, alt and description (there are at least 2 ways). Can you post a screenshot too?

I fill it while writing the post. https://4.1m.yt/9cQLo1OVE.jpg

Should be good. Did you try it checking it without the Jetpack gallery active?

I just did and now the titles are showing.
Don’t you know why? Because I’d like to use tiled mosaic type of gallery.
