Default GameObject Tag Already Registered

Can anyone tell me where to look for the following error?

Default GameObject Tag: banana already registered
UnityEditor.SerializedObject:ApplyModifiedProperties()
UnityEditor.SerializedObject:ApplyModifiedProperties()
UnityEditor.Editor:OptimizedInspectorGUIImplementation(Rect)
UnityEditor.GenericInspector:OnOptimizedInspectorGUI(Rect)
UnityEditor.InspectorWindow:OnGUI()

System.Reflection.MethodBase:Invoke(Object, Object[ ])
UnityEditor.HostView:Invoke(String)
UnityEditor.DockArea:OnGUI()

[…..\Runtime\BaseClasses\Tags.cpp line 52]

I am getting this error but don’t know how to solve it.

Any help?

I would be interested in knowing what the answer to this is as well. Has anyone figured it out? Not a big issue for me at the moment, but would like more info.

I am also getting this. I am not sure what it is about, but I’ll let you guys know as soon as I find out.

EDIT:
Renamed the tag “banana” to “banana1” and restarted unity.

After restart, there were two tags, “banana” and “banana1”. Error was no longer there.

There must be the duplicate tags’ name in your ‘Tags & Layers’ in your Inspector, please check it
