This voicemail issue has happened to me several times. I run into this sometimes because I don't listen to a whole message prior to deleting that message. If your indicator is stuck on here's a quick way to fix the issue. Call your phone number from another device leave a quick message then from your device, call your voicemail and listen to that message and erase it. This should reset the indicator. Let me know if that helps.
