Problem With New Post – Custom Fields Already Filled In With Old Files

Each time I write a new post, I get a ton of pre-filled custom fields. They’re filled with unrelated images, thumbnails, and such that were uploaded quite a while ago to different posts. I do not want them to be pre-filled and they are seemingly filled with random files.

It takes quite a while to load the “new post” page because of these pre-filled custom fields.

This problem started to occur right after we swapped the location of the website. It was located at https://www.first.com (example) and moved to https://www.second.com (also example).

Prior to the move, I was able to write a new post quite rapidly and none of the custom fields used to be pre-filled.

Using 2.6.3

If you can help, thank you!
