Can't hide date on K2

I have installed the Music template and using K2 component. I setup a parent category (Category 1) and two child categories (Category i, and ii). Child Categories inherit parameters from the parent category.
I have hidden all the "Create time and date" in every category as well as in the component parameters to hide the date on the Category list view. Unfortunately, the date still shows on the category item list view.
I appreciate if someone could help me to hide this date.

Thanks in advance.
