### Prerequisites

- [x] I have searched other issues and found no duplicates

- [x] I want to report a bug and not [ask a question or ask for help](https://github.com/AdguardTeam/AdGuardHome/discussions/categories/q-a)

- [x] I have set up AdGuard Home correctly and [configured clients to use it](https://github.com/AdguardTeam/AdGuardHome/wiki/Clients). (Use the [Discussions](https://github.com/AdguardTeam/AdGuardHome/discussions/categories/q-a) for help with installing and configuring clients.)

### Platform (OS and CPU architecture)

Linux, ARM64

### Installation

GitHub releases or script from README

### Setup

On one machine

### AdGuard Home version

0.107.68

### Action

Client Settings > Identifier - first identifier box needs a [X] delete button when there's more than 1 identifiers
1) Add a Client Settings, name it "test"
2) Enter "127.0.0.1" for example, then save to close it
3) Go open "test" Client Settings, then add second identifier 10.0.0.1, then save to close it again
4) Go open "test" Client setting again, 10.0.0.1 moved to first identifier. Now if I want to delete 10.0.0.1 and only keep 127.0.0.1. it cannot be deleted. I have to replace 10.0.0.1 with 127.0.0.1 and then delete the second box.

### Expected result

[X] button should appear for first identifier.

### Actual result

No [X] button appears for the first identifier AND it automatically sorted the identifiers alphabetically. So to delete the first one, it needs to be replaced with content of second identifier and then delete the second identifier.
