First of all, when I am trying to create a new k2 item the publishing date is not populated automatically. This is the first time I noticed such an issue in a Joomla backend.

When I choose a future time for publishing date and wait for this time, the item is not displayed in any mod_news_pro_gk4 module.
On the other hand, if I am not choosing publishing date, the article is displayed normally.
Could anyone help me to resolve this?
