Hello,
1. On our layouts page (and other similar pages), we use the default WordPress sorting for posts, which returns all layouts relative to their conditions. WordPress sorting by default sorts by date of creation from new to old, and this behavior can’t be easily changed with WordPress themes only.
2. To check this issue, we need valid admin access. Please share the login details in the private content area.
3. This question is not clear enough, can you please explain it in more detail, possibly with video or screenshots?
Best Regards.
