The Test Object name is displayed correctly in the Katalon UI but automatically changed in the back-end of the project and in the recorded script. May I know why the name changes without any interruptions.
Please find the screenshots:
Repository name in Katalon UI:
I dont know if I understood this right but, The name of the objects is not the way the (for example) input field is called by katalon its only the name you saved while recording.
When you double click the object it will open and you can see most likely the xpath its using for this object.
