Recurring Gift Notifications

I've always wondered this, but what causes some gift notifications to come back again the next day? I originally thought that it occurred only when someone sent you a gift the previous day and they were maxed out on gifts when you tried to gift back. But some of the ones that pop up seem to be ones that I'm almost certain that I successfully gifted the day before. I know it's an old one because there is no option to accept or decline and the time stamp is usually like 22 hours ago or something really weird. Anyone know if this is just some glitch that happens to everyone or is there a method of gifting people that will prevent this from constantly happening? Is it when the gift gets declined?

I'm having the same issues. Im using Android 4.1.2, Model:SPH-M840 Restaurant Story Version: 1.5.5.7.8 (I hope that's right)

Its normal. It's a list of your accepted gifts. I guess it's there to remind you it's time you can gift again.

Send gifts to your neighbors and the messages will go away.
