Hello there sbritprovectus! 👋

Thank you and congratulations 🎉 for opening your very first issue in this project! 💖

In case you want to claim this issue, please comment down below! We will try to get back to you as soon as we can. 👀 Almost all fields are not set according to the actual values but rather contain the widgets default value. I'm happy to take a look at this.
I'm not sure why this is here. I can see you reassign it `formInit = false;` on line 79 inside useEffect. This is not a good way to do, instead use useState, or if you don't need to trigger rerenders use useRef to store this variable. Just create a ./fixtures file somewhere near this test file to separate such huge objects from the tests. ```suggestion
const startParams: TopicWithDetailedInfo = {
``` ```suggestion
      source: ConfigSource.DEFAULT_CONFIG,
``` check this file. We already have fixtures
```
src/components/Topics/Topic/Edit/__test__/fixtures.ts
``` pls cover all the cases it is not complex it returns default values when topic is not defined describe maxMessageBytes
 - it 
 - it convert to number
 - it returns default value when  test case ```suggestion
    it('returns completed values', () => {
``` pls fix it for all cases ```suggestion
    it('returns transformed values', () => {
``` ```suggestion
        transformedParams.partitions
``` move payload to fixtures file I would prefer to move `|| -1` logic inside of `getValue`. So add one more `defaultValue` param ```suggestion
    it('returns transformed value', () => {
``` ```suggestion
    it(`returns default value when ${name} not defined`, () => {
``` ```suggestion
    it('returns number value', () => {
``` ```suggestion
    it('returns value when field exists', () => {
``` ```suggestion
    it('returns default value when field does not exist', () => {
``` ```suggestion
    it('returns value when filed name does not exist', () => {
``` ```suggestion
    it('returns transformed value', () => {
``` ```suggestion
    it('returns default value when partitionCount not defined', () => {
``` ```suggestion
  describe('customParams', () => {
    it('returns value when configs is empty', () => {
``` Are you sure we can use `-1` by default? ping @Haarolean  Uuhm is that like for all the int params? Seems dangerous. How did it work before? I added that. There was no such thing. ```suggestion
  defaultValue?: string | number
``` returns
[Topics] There are default values when user try to edit topic
**Describe the bug**
When user try to edit topic after creation there are defaults values in edit topic settings view


**Set up**
Local docker.
App version: Version:v0.3.3(38c4cf7)


**Steps to Reproduce**
1. Create topic (e.g. using API)
2. Go to newly created topic
3. Go to Edit Settings
4. Edit something (e.g. change Cleanup policy)
5. Save
6. Go to Edit settings again
7. Observe the view

**Expected behavior**
At Edit settings view should be current topic's values

**Actual result**
All setting are default
