Version 2.1.5 breaks user list display

Hi, I upgraded to version 2.1.5 yesterday, and after doing so, my user lists no longer display the proper users when a role is selected. For example, if I click “Administrators”, it lists all of the users, not merely those who have Administrator access. Fortunately it doesn’t appear to have actually granted said access, but it was still a bit alarming to discover this morning, especially as the WordFence security plugin proceeded to email me with a list of several thousand customers who were suddenly showing up as admins.

I rolled the Pretty Links plugin back to version 2.1.4, and the user list is now behaving properly again. I am using WordPress version 4.9.4 and WooCommerce version 3.3.3.
