Logs fine, display is wonky

I set this up in conjunction with WordFence to a) be able to see if anyone had logged in recently (in case I needed to bounce the Apache server) and b) track failed login attempts for fictitious users. It logs just fine — and is doing a great job of capturing even failed login attempts (much to the benefit of my WordFence filtering), but… the view as a Network Admin does not actually scroll through different logins — it looks like it should (it even tells me it’s on a new page), but the actual login list is not refreshed. But the data’s all there in the wp_simple_network_login_log table, so I’m just fine.
