iPhone/Airpods Mute Announce Notifications not Working

I have added the Announce Notifications button to my iPhone control panel. When I open the control panel and press it, I have the options to have Announce Notifications On, Muted for 1 hour, or Off for the day.

Problem:

I open the control panel, select Announce Notifications, and choose Mute for 1 hour. The app closes and takes me back to the control panel (so far that's normal). I go right back into the Announce Notifications app and can see that notifications will be muted for 1 hour until 2:20pm (for example). Minutes later, I get a text and Siri reads it to me even though announcements are supposed to be muted for 1 hour! I go back to the control panel and I see that Announce Notifications has reset to On. It's almost as though getting a new texts shuts off the Mute for 1 hour option I have selected.

I have rebooted my phone, and the problem persists. My iPhone is completely updated. What is going on here? Every time I get a text or calendar pop up it's reading it to me despite my repeatedly selecting Mute for 1 hour. I'm going to shatter this phone against the wall if it doesn't allow me to mute notifications for 1 hour. I need my airpods in for the work I'm doing but I can't shut off these $@&#$^$ notifications!!!!
