Help needed for notification badges for third party apps on galaxy s5

[Fly78]

Hello,
Can anyone tell me how to disable or permanently get rid of the notification badge(message counter on the app icon)?I have a samsung galaxy s5 and it keeps showing for a thrid party app,for example LINE messenger.I've tried to disable all notifications from this app but the badge keeps working.It only appears on this particular phone,so it must be a software issue I suppose.Is there a way to disable this badge or am I stuck with it no matter what?
Thank you in advance
