I don’t see the options I select
The reason you’re not seeing these options on the front-end (comments count, views, etc) is because the theme you’re using, Tiles, doesn’t include them. You’d need to modify said theme (see the Post HTML markup field from your previous screenshot) to have it display this information (see Content Tags.)
do you have any idea how I can solve this full screen problem?
You could try inserting your Popular Posts block inside a Columns block. Might need to play around with it to have your popular post list not use the entire width.
Alternatively, you may also want to reach out to the developer of your WordPress theme and ask them what’s the best way to deal with this particular issue.
