Category menu products not showing

I want to display all the products listed under a category and it was working well before but it suddenly stopped showing products in the category. Have tried many different settings but to no avail. I have made screenshots of the current settings.

Please help.

Thanks!

Hi,

The settings are ok. It must come from something else.
Can you do a screenshot of the products listing of that mix and match category in your back end and give a link to the products listing menu of your front end ?
