When i add pady on the second button, that will move the both button in the row.
version = "5.1.2"
self.export_txt=CTkButton(self,text="EXPORT",command=lambda:self.txt_export())
self.export_txt.grid(row=2,column=3)
self.lic_reload=CTkButton(self,text="lic_reload",command="")
self.lic_reload.grid(row=2,column=3,sticky="s",)#pady data will move both widget
Is that intentionell that you put both buttons in the same cell? Because you overlapp them like that and then it would be totally normal that they behave the same.
