   In "tkinter.Chechbutton()" and "tkinter.Radiobutton()" widgets if the "tristatevalue" option is set to an empty string the indicator appears the first time in the 3rd state in which it is gray, but if I check the button multiple times I can't put the indicator again in the 3rd state, and if I set the "tristatevalue" to other value the indicator doesn't appear in the 3rd state

Thank you for your help
