Out of stock products are showing

I’m using the free version of your plugin on my front page. Loving the results thus far. However one thing is puzzling me, i have turned the hide out of stock products option on and out of stock products are still showing in the front end with the ‘more information’ button.

My website language is in Dutch, is this a language related error? Maybe it has to do with the recent wordpress or woocommerece updates? Hope you can help. Thank you.
