Describe the bug

I have a listbox like

 <p-listbox [filter]="true" [multiple]="true" [checkbox]="true"
                    [metaKeySelection]="false" [(ngModel)]="filterConstraint.value" [options]="c?.filterOptions??[]"
                    class="time-series-filter-listbox"></p-listbox>

I am encountering the same problem. I have made a stackblitz for it here: https://stackblitz.com/edit/gjuaa6?file=src%2Fapp%2Fdemo%2Flistbox-filter-demo.html

Have yet to figure out a workaround that isnt just using the label, value format
