Dear Sufiyan Challiwala,
Thanks for posting in Microsoft community. We are glad to help you.
Based on your description, may I know your MacOS version and Office version? Could you attach a screenshot of the paste option on your side?
To copy and paste the slides with formatting, please use Ctrl+click or right-click the thumbnail you want your copied slides to follow in the second presentation, click the Paste Options button that appears, and then click Keep Source Formatting. This implies that the slide will keep its original theme format.
Thank you for your understanding and cooperation! Have a great day.
Sincerely,
Sean | Microsoft Community Moderator
