Today I noticed that a calendar event (see below) started showing up in my ESV Bible:

For clarity, I'm referring to the light blue text "Kingdom Warrior Prayer E..." to the right of the calendar's "24 icon" at the bottom. Traversing Settings doesn't reveal a way to remove it. tapping on it, and even adding it to google calendar doesn't make it go away. Please help if you know how to stop those intrusive Kingdom Warriors!
