Hey Michael! We've had this issue before where something got "stuck" in our critical range setup. If you click the settings cogwheel in the combat tab, clear out that critical range input, save, and then reopen, it may show you a new value that you can then clear out and save again. If you do that, is it fixed? Can you share your class/species/background so we can look further into what's causing this bug? I've only seen it once before and we haven't been able to get a consistent reproduction yet.
