### Summary
When creating a new MR approval rule in a new project with `Approvals required` greater than `0`, the current row gets duplicated. This row disappears after a refresh of the page.
### Steps to reproduce
- Create a new project
- Go to `Settings` -> `Merge Requests` -> `Merge request approvals`, and change the value for `Approvals required` from `0` to `1`. This will create a duplicate line, which will disappear when refreshing the browser.
### Example Project
This happened for my example project with project ID `69064828`, but also for all other new projects in the same subgroup. However, as the duplicate line disappears after a refresh of the page, it is no longer visible. See screenshot attached to this ticket of when it happened.
### What is the current *bug* behavior?
See above. When creating a new MR approval rule in a new project with `Approvals required` greater than `0`, the current row gets duplicated. This row disappears after a refresh of the page.
### What is the expected *correct* behavior?
When creating a new MR approval rule in a new project with `Approvals required` greater than `0`, the current row should not get duplicated.
