AS923-2 shows as EU868 in Application server v3.17.6

[IoTThinks]

• [x] The issue is present in the latest release.
• [x] I have searched the issues of this repository and believe that this is not a duplicate.

What happened?

The application server v3.17.6 and network server v3.16.1 for AS923-2 still show as EU868. This issue is applicable for all AS923-2, AS923-3 and AS923-4. While the wording is incorrect, the functionality for AS923-2 works fine. This issue happened since Network server v3.15.3 https://forum.chirpstack.io/t/as923-2-shows-as-eu868-on-network-server-v3-15-3/12579

Other AS923 and EU433 are shown correctly OK.

What did you expect?

It should show AS923-2.

Steps to reproduce this issue

Steps:

1. To add a Network Server with AS923-2/3/4.
2. To see if it incorrectly shows as EU868
