Hello Ladyjae23,
I understand you're getting some alerts from the App Store saying specific apps are no longer assigned to you. I'm happy to help you out with this.
Did you recently uninstall a configuration profile, or do you currently have profiles installed on your iPhone? If you aren't sure, you can check in Settings > General > Profiles & Device Management. It's possible you could be seeing these alerts due to content managed through that profile. Apps can be remotely assigned and unassigned.
Thanks for using Apple Support Communities.
Take care.
