iPhone Help! My Today view Widgets are not working properly!

I have an iPhone 6 Plus on iOS 8.1 and I thought upgrading from 8.0.2 would fix this problem but it didn't. My Today widgets don't seem to work properly. The Yahoo Weather widget is empty and randomly flashes what it is supposed to display correctly, but for like half a second before becoming blank again.

The Reminders widget doesn't even show up even though there should be 2 reminders. The weather information in the Today Summary doesn't appear either. I've tried installing Wdgts and only half of the widgets show up even though I've selected all of them.

Is there a fix for this or is this a known bug? I've tried restarting the phone and what not, but the same problem is still persisting.
