Got Row Null error while importing test case to Jira using Zephyr

Please check the photos above. I believe I did the mapping correctly. The imported excel file has only two rows, but none of them could be imported

If I skip the Step field, it could be imported successfully, but the step field will remain empty, which is useless for test case.

I also see the same issue. I have test cases separated by an empty row in the Excel sheet and using the Discriminator "By Empty Row" and getting null error.
