Remove button removes last item of a collection instead of current

Hello,

I'm using Bonita 7.13.0 and in the UI Designer, when I set a collection of "AutoComplete" input fields, the "remove" button associated to this item (=the current) removes the last item of the collection (instead of the current).

If I leave the field "available values" empty (instead of setting my object list variable) it works as expected.

Can you tell me how can I fix this bad behavior ?

Thank's
