Repeating Local Notifications on Android

we are using the Local-Notification Plugin quite successfully, but recently we heard from 2 users a strange and concerning bug. When they got the message and tried to swipe it to remove the message from the message board, the message came bag immediately. Unfortunately we were not able to reproduce the bug in any way, but got a report of the issue of two independent users. Has anybody had the same issue or has an idea what we can do? Thank you.
