CustomPress: CPT not showing date published

I have a simple custom post type (CPT) created by CustomPress.

I'm showing these custom post types at default blog loop.

At single site settings, there is CustomPress-settings, where I have selected these:

On "Blog / Home" page, display these post types:
- posts, mycustomposttype

That's fine. I can see my CPT-posts.

BUT I can not see the date they are published.

I use special 'posted_on' function. I tried to remove it and use themes default 'posted_on' at my content.php

I use _s (underscores) theme. Guess that doesn't matter..

Shouldn't it just show the date, when it's already using the default content.php, single.php etc..?
