Style lost when cloning slide

[andreacalvi]

Hi I am trying to clone this template but style gets lost in the process.
Is there anything that I am missing?

Sample code here with template just run it to see the output and differences in styling

Hello,

Thanks for your inquiry. I have checked your document and found that the reason for the different styles is that the themes in the source document were not copied into the new document. I have recorded this problem in our bug tracking system with the number SPIREPPT-2646. Our dev personnel will further assist in troubleshooting, and I will notify you immediately once there is progress.

Sincerely,
Amin
