Test Case changed to empty if move from one folder to another

All my cases are in project A. If I only copy test cases from project A to Project B test case folder. When I open the test case, it is empty without any step.

Did you ever meet such issue? How to resolve it.

Issue also happened if I move cases from one folder to another folder even in same project.

hello,

try to cp all in script view mode

Yes, I know that should be ok. But I have many cases need to execute, It need a lot of work to do . Do you know another way to make the cases avaliable?

hello,
not sure, try to cp needed files from project folder to another project folder using file explorer

You have to copy the respective file from the Script folder too.

Inside the Script folder, it store all the groovy script.
