Why won't the Control Center module let me turn on Airdrop on my iPhone 8?

This has worked before in the past but I don't know why it doesn't work now. I used to be able to turn Airdrop on/off on my iPhone by: 1. Swiping up from the bottom of my phone 2. Pressing and holding the module that has options for Airplane mode, WiFi, etc. (image of what I'm talking about here on google ) For some reason, now when I press and hold that module, it doesn't open up to let me turn Airdrop on/off or turn on my personal hotspot. I've tried powering off/on my phone, and closing all apps but nothing is working. I don't know what else to try. Is there some app that I installed that might have prevented this from working as usual? What can I do to make this simple function work again?
