Remove redudant data from master data

Hi, anyone know how to remove the data after it has been selected?  For example, for the first form, I select the first item, for the second form, I want the items that been selected disappear from the list.

If this is a reference selector you will need to use a microflow as datasource. In your microflow retrieve only the objects which are not yet connected + the one which is possibly selected (for editing existing data, otherwise you association will get set to empty)
