Draft products showing on homepage

[commonground]

Hi everyone, 

I am having a problem with my prestashop 1.7.6.2. 

In a nutshell, if I add up a new product to my catalogue, and then for some reasons I decide to leave it a draft and don't save it, the product still shows up on the homepage as if it was a product I completed and saved. To make it worse, in my backoffice, if I go to "catalog" to remove it from there, it's not there! So it's like a ghost product that shows on the front home page but not on the back office. Is it a prestashop bug or what? I know there must be a way to delete these draft products directly on the database somehow, but I would like to avoid that everytime I start work on a new product page and then I discard it prestashop automatically save it and add it up to the homepage regardless. 

Any help would be really appreciated.
