Textfieldentry isnt saved

Hello,
my Problem: if i write something in the Textfield from a Task, go to another Task and back to the first, all Words i just wrote are gone.
The textfield is a extension to the standard “general-group”.
I update my general group like this:

function updateGeneralGroup(groups, element) {

  const generalGroup = findGroup(groups, 'general');
  if (!generalGroup) {
    return;
  }
  const { entries } = generalGroup;
  //change the name of the group
  generalGroup.label = 'Allgemeine Angaben';
  // (1) add version tag before executable (if existing)
  const executableEntry = findIndex(entries, (entry) => entry.id === 'isExecutable');
  const insertIndex = executableEntry >= 0 ? executableEntry : entries.length;
  if (!is(element,( 'bpmn:Process' ))) {
    entries.splice(insertIndex, 0, ...AllgemeinstartProps({ element }));
  }
  if (is(element, 'bpmn:Process')) {
    entries.splice(insertIndex, 0, ...AllgemeinProps({ element }));
  }
  
  const updatedEntries = entries.filter(entry => entry.id !== 'id' ); // remove id entry
  entries.splice(0, entries.length, ...updatedEntries);

}

My AllgemeinPropsStart look like this:

import {
  getBusinessObject,
  is
} from 'bpmn-js/lib/util/ModelUtil';

import { TextFieldEntry, isTextFieldEntryEdited } from '@bpmn-io/properties-panel';

import { useService } from 'bpmn-js-properties-panel';

export default function AllgemeinPropsStart(props) {
  const {
    element
  } = props;

  const businessObject = getBusinessObject(element);
 

return [
    {
      id: 'Nr',
      component: Nr,
      isEdited: isTextFieldEntryEdited
    },
    {
      id: 'Verantwortlichwe',
      component: Verantwortlicher,
      isEdited: isTextFieldEntryEdited
    }
  ];
}

function Nr(props) {
  const { element } = props;
    const translate = useService('translate'),
          debounce = useService('debounceInput'),
          modeling = useService('modeling');
        

    const getValue = () => {
      return element.businessObject.Nr || '';
    }
  
    const setValue = value => {
      return modeling.updateProperties(element, {
        Nr: value
      });
    }
  return TextFieldEntry({
    element,
    id: 'Nr',
    label: translate('Nr'),
    getValue,
    setValue,
    debounce:debounce
  });
}
function Verantwortlicher(props) {
  const { element } = props;
    const translate = useService('translate'),
          debounce = useService('debounceInput'),
          modeling = useService('modeling');
        

    const getValue = () => {
      return element.businessObject.Verantwortlicher || '';
    }
  
    const setValue = value => {
      return modeling.updateProperties(element, {
        Verantwortlicher: value
      });
    }
  return TextFieldEntry({
    element,
    id: 'Verantwortlicher',
    label: translate('Verantwortlicher'),
    description: translate('Name'),
    getValue,
    setValue,
    debounce
  });
}

I also have a “AllgemeinProps” because i need diffrent properties for the whole process and the task. So i use “AllgemeinProps” just for “Process” and “AllgemeinPropsStart” for the rest.

thxx for helping!
