Error on delete all or delete last

Hi again,

Still playing with your fantastic plug-in. I found a beta version on Gitehub and mixed some codes. It seems almost all functions work now. Although 2 things are still unclear. I hope you can help me.

1. When I select 4 items to the list, they all show up, perfect! After that I delete them, 1 each time. Now, the last one or the button “delete all” gives me an error. See attached screenshot.
2. On the page where I can select the posts i want to add to the list, the hearts will not be coloured if I go back to that page after surfing. So, you cannot see which items are already selected unless you visit the list with the selection.

I am not a great programmer so if you have a solution, keep it simple. I always say, “talk to me as if I where 5 years old”. (lol)

Thanks again and a Happy New Year!
