error vote

hi, why did I have 2 votes instead of 1? The first was in two days, and the second is now.

Failed to call hook 'cmdVote' on plugin 'MapVoter v1.4.68' (IndexOutOfRangeException: Index was outside the bounds of the array.) at Oxide.Plugins.MapVoter.cmdVote (Oxide.Core.Libraries.Covalence.IPlayer player, System.String cmd, System.String[] args) [0x000a6] in :0 at Oxide.Plugins.MapVoter.DirectCallHook (System.String name, System.Object& ret, System.Object[] args) [0x01b03] in :0 at Oxide.Plugins.CSharpPlugin.InvokeMethod (Oxide.Core.Plugins.HookMethod method, System.Object[] args) [0x00079] in :0 at Oxide.Core.Plugins.CSPlugin.OnCallHook (System.String name, System.Object[] args) [0x000d8] in :0 at Oxide.Core.Plugins.Plugin.CallHook (System.String hook, System.Object[] args) [0x00060] in :0
