Drop-down not selecting new value on change of mat-selection-list, works only for the fist time

  angular, dropdownbox, select

I am using mat-selection-list, so once I click on a row .based on the list value I m generating drop-down list . On change of the selection in mat-selection-list list , I am emptying drop-down list and again generating the new drop-down list and selecting particular drop-down value.
The issue is first time the list update the drop-down list and select the value. But on change of mat-selection-list it don’t update the drop-down.

In elements tab I see we have options for that drop-down elements but it’s not selecting the patchvalue
