when I am selecting level as account or device in my angular component GL Code placeholder is displaying blank without message"select GL CODE"

GL Code Name*

{{ 'Select GL code' | translate }} {{element.GL_CODE_DESC}}

      <small *ngFor="let validation of errorMessages.gl_code_id" class="text-danger">
        <span *ngIf="
                  chargingForm
                    .get('gl_code_id')
                    ?.hasError(validation.type) &&
                  (chargingForm.get('gl_code_id')?.dirty ||
                  chargingForm.get('gl_code_id')?.touched)
                ">
          {{ validation.message }}
        </span>
      </small>
    </div>
  </div>
