Multiple option dropdown not showing default value

I am working on a multiple dropdown with default values (provided by a back-end API). I am inspecting my element and it shows that it has default values, but the actual input area doesnt have these items in the input session. These item values are available in the dropdown menu. For example, I have preselected the “general” tab, and it is showing in the dropdown menu and not the default value


and here is my setup. I am returning the same data type. In the choices source, I am calling the same function leaving the channel_ids as blank.

I didn’t test it out, but is a Multidropdown not a list? So you need to use plus item?
