Too many notifications

I have push notifications enabled and there is a bug. My client checks in and i get notified, thats fine, but throughout the day ill randomly be notified multiple times that my client is here even though they left hours ago. Every time one client gets checked in I get notified for all the past clients as well. This is extremely annoying and makes it difficult to use my phone regularly when I get alerted so many times. Pleeease fix this bug!!!
