BuddyPress.org

Hi, I am using Buddypress v14.2.1 together with BuddyPress Xprofile Custom Field Types v1.2.7 to be able to use select2 with a Multi Select Box field in user profiles.

It seems that select2 works correctly as I get a text field in which when typing, the autocomplete function acts and recommends me some option from my list. The problem is that when I select an option, instead of being added in tag format and I can continue typing in the text field to add more options from the list, a tag containing all the options from my list is added and the text field disappears, so I can not continue adding option from my list.

Here is my multi select box field configured to use select2 as you can see in this picture in the top right corner:

As you can see this new picture, if I access the field and test the autocomplete filter, it seems to work correctly. But when I select an option, this happens and I can not do anything, I can not write to add new options or anything:

What could be happening? Thanks in advance.
