All the loading bars have the same id: #loading. When clicking on buttons, they are added and shown for 3 seconds, then they are just hidden instead of being removed from the DOM. So, multiple instances with the same #loading id may be present at the same time, and the callback function will always hide the first one, which is the already hidden bar under the Add/Remove checkbox button.
