Hi, I used the Forum to create a section dedicated to the exchange of 520 collectible pieces by creating a discussion for each collectible piece, with the hope of simplifying the research work for users of the site.

I put each item in both the "sell" and "search" sections, creating a total of over 1000 threads.
unfortunately a few steps from the last discussions, I can no longer save the order of the forum hierarchy (gif attached).
I have made several attempts to try to solve the problem but without success, I would like to ask you if you have any idea what the problem may be

Thank you all!
