multiple UI bugs

[Wolfplayer]

When I enter the game, these three windows appear with error:

Failed to create control 'LibCustomMenuSubmenu'. Duplicate name. stack traceback: [C]: in function 'CreateControl' user:/AddOns/FCMQT/Libs/LibCustomMenu.lua:85: in function 'Submenu:Initialize' user:/AddOns/FCMQT/Libs/LibCustomMenu.lua:78: in function 'Submenu:New' user:/AddOns/FCMQT/Libs/LibCustomMenu.lua:648: in function 'OnAddonLoaded'

ResizeToFitDescendents: Enabling resizeToFitDescendents is illegal for Label . stack traceback: [C]: in function 'SetResizeToFitDescendents' user:/AddOns/FCMQT/FCMQT.lua:1067: in function 'FCMQT.Init'

Could someone help me to resolve this?
