Boot Runner not performing consistently on Mojave

Hello,

After updating one of our MacBooks to 10.14.5, BootRunner stopped working consistently. Before, every logout, restart, or boot up would launch the BootRunner menu. Now, sometimes after restarting it will not load until after we have entered credentials to get into the macOS partition and sometimes after logging out, the BootRunner never appears. We are using version 3.1

I just tested Boot Runner 3.1 again on 10.14.5 and it rebooted it 5 times, and Boot Runner came up each time. Is it possible that something is conflicting with it? Can you try testing on a system that has a fresh install of 10.14.5 and boot runner installed (and nothing else) and see if it still happens?
