In my version of Katalon Studio, a name of a Test Object has to be different more than by lettercase. In other words, it does not matter if a specific letter is lower case or upper case, they are the same (i.e. “b” is the same as “B”, “c” is the same as “C”, etc.). How about append a number to the end of the copied object as an example to see if this is your concern. (eg. …_btn1)
