### Describe the bug

currently the cms has 4 records

which generates the id field with text extended from a different row. possibly due to size limitations from https://github.com/aws-amplify/amplify-studio/issues/925

### Expected behavior

generate csv in the correct format

### Reproduction steps

1. create a model with for example:
```
type User @model @auth(rules: [{allow: public}]) {
id: ID!
status: AWSJSON
}
```
2. open CMS and select auto generate with 5 records(for example)
3. download to csv and observe the data

Reproduce the export in CMS using the shown User model with an AWSJSON field and several generated records. Start by tracing the CMS download-to-CSV path and compare the generated rows with the behavior referenced in issue 925. Done means each record produces a correctly separated CSV row without text from another record.
