Could someone help me with these blocks for adding and removing itens from my list?

It seems very basic but I really don’t know what’s wrong with my blocks, could someone point my mistake on why my itens are not being removed from the list and everytime I click to remove it ,it shows the alert notice “…removed” but it does not remove any item at all and does not show any error.

These are the blocks:



Here is my screen test:

I used some colors to differentiate …

When I first click the VISIBILITY icon,it turns green and the item is saved in the list,okay. But when I click again in the same icon,it turns to pink and shows notice “removed” but it is still in the list and if I click again it keeps showing “removed” and does not change the color to green and notice to “watched”.

Thank you in advance!
