BTT No Longer Recognizes CTRL Modifier Key

One of my Keyboard Shortcuts stopped working a week or so ago - possibly after a macOS Beta update. This shortcut used CTRL-OPT-CMD-[DELETE] as a trigger. When I opened BTT to see what was going on, I noticed that the "Click here to record a shortcut" field would not show an entry if I held those four keys down. However, other key combos still worked - e.g. SHIFT-OPT-CMD-[DELETE].
