Notification red bubble

Issue: Having an issue whereby every time I have a Monzo notification the red numbered bubble shows 2 notifications despite there only being 1. I can’t find the second anywhere in the app. Any ideas what this could be? I have deleted and reinstalled and still the same!

Details to reproduce: make a transaction
OS: 17.6.1
Device: iPhone 15 Pro
App Version: Latest
