Hi KCSR,

Thank you for posting in Apple Support Communities!

We have a few questions to help the community get a better understanding of what you're experiencing. What app is this happening in? What iOS do you currently have installed on your iPhone? Do you have a recent backup of your data?

You can also try some basic troubleshooting steps that can help when we experience unexpected behaviors.

1. When an app is not behaving as expected, closing it out and relaunching it can help. Check out how to do so here: Close an app on your iPhone or iPod touch- Apple Support
2. Restart your iPhone: Restart your iPhone- Apple Support
3. Check for app updates: How to manually update apps on your Apple device- Apple Support
4. Check for iOS updates: Update your iPhone or iPad- Apple Support

Hope that helps!
