validationErrors: submit is enabled even if function return false

I've implemented a function that verify validity of other forms in page, if the form generated from JSONSchema is valid the Submit button is enabled even if other forms are invalid (the function returns false)

which template:

[ X ] MaterialDesignFrameworkModule — Material Design

To Reproduce

<json-schema-form #schema_form loadExternalAssets="true" [schema]="jsonSchema" language="it"
                framework="material-design" [layout]="formLayout" (onSubmit)="submitForm($event)" [widgets]="myWidgets"
                [options]="exampleJsonObject" (isValid)="validFormFn($event)"
                (validationErrors)="validationErrorsFn($event)" [debug]="false">

   </json-schema-form>

validationErrorsFn(event: any): boolean {
    const docFormArray = this.form.get('documentsForm') as FormArray;
    let validDocs = true;
    if (docFormArray) {
      validDocs = docFormArray.valid || false;
    }
    let eventValid = true;
    this.jsonFormError = [];
    if (event && typeof event === 'object') {
      eventValid = false;

      event.forEach((x: any) => {
        this.jsonFormError.push(`${x.keyword} - ${x.message}`);
      });
    }

    const validForm = validDocs && this.privacyOk && eventValid;
    this.validForm = validForm;

    console.log('validForm: ', validForm);

    return validForm;
  }
  validFormFn($event) {
    console.log('Called validFormFn from: ', $event.toString());
    return this.validForm;
  }

Expected behavior The submit button is disabled
