I am creating a discount with the target "Apply to Product", then when I'm trying to select what products my discount applies for. I select a few products and click add.

I get the "Success: Your request completed successfully." message, but the product I just added to my discount is not displayed on the list. I tried to reload the page with no success, still no products in the list.

 

I have verified the same behavior on my colleague's machine. We are both running Liferay 7.2 SP2 with Commerce 2.0.7
