Thank you very much for fast response and fix !
Also i just want to let you know i found another minor bug, where if you click Expand Text edit , it seems not doing anything and it gives error messages in Output :
ERROR: core/object/object.cpp:1249 - Error calling from signal 'pressed' to callable: 'Control(main.gd)::_on_text_edit_expand_button_pressed': Cannot convert argument 1 from Object to Object.
