Hello RenaieH,
Welcome to the Apple Support Communities. I understand you're seeing a persistent Calendar invitation notification.
This may come up if there was an unsuccessful attempt to respond to a Calendar invitation. To clear this up, try tapping Settings > Passwords & Accounts. Under the "Accounts" section, look for any listed accounts that have Calendars turned on. Toggle all of these calendars to off, and then Restart your iPhone, iPad, or iPod touch :
I hope these steps help.
Take care.
