1. Fixed this issue
2. Working on this right now. Making repeatable WYSIWYG editors is ridiculously difficult unfortunately and wp_editor() doesn’t allow itself to be repeatable, so I have to mimic the editor using HTML instead of the function. This makes it so the core editor and the Sections editors don’t work exactly the same.
I’m going to release an update today that fixes #1 and a couple other issues.
The fix for #2 will come after, but hopefully it won’t be long.
