Please note in this forum we mainly support Office for Windows, as your question is about Office for Mac, I suggest you post the question in Office for Mac forum for further assistance:

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
