Hello again, 
Guys, it's like this....
I followed the suggestion that was given to me here, however I have tried everything and it happens that now the two values(strings) appear inside the button, the condition that I created is not working, it should appear only one, according to the name that is inside the picking_type_name, but it won't...
I don't know what to do anymore... 
I know that in this print is the.picking_type_id.name, but before it was the.picking_type_name and gave the same problem with the two values inside the button...
Help 😦
