I attempted to replicate the issue and find similar cases, but unfortunately, I could not find anything similar. In this case, my suggestion would be to clear your cookies and cache, ensure that you have the correct permissions to clone design templates, and check that the template is not locked.
I hope this helps, but if not, please let me know.
Thank you so much for trying out the different options and providing me with your feedback!
In this particular situation, I believe that further investigation is required to provide you with the best possible assistance.
To proceed with the investigation, could you please send me a Har file via direct message (DM)? This will allow me to thoroughly review the information and better understand the issue at hand. Once I have the file, I’ll be able to analyze it in detail and provide you with a more accurate solution.
