bug(mac): Installed EuroLatin(SIL) keyboards for French and German are missing in the Keyboards menu list

### Describe the bug

I noticed that after adding French and German EuroLatin(SIL) keyboards the installed keyboard is only showing one EuroLatin(SIL) keyboard.

### Reproduce the bug

1. Install Keyman 17.0.142-alpha build in macOS.
2. Open Keyman Configuration dialog.
3. Click the Download keyboard button.
4. Install EuroLatin(SIL) keyboard for French.
5. Install EuroLatin(SIL) keyboard for German.
6. Open Keyman menu from the taskbar.
7. Click 'Keyboards' list menu.

Here, I noticed that there is only one 'EuroLatin(SIL) keyboard appear in the Keyboards list. Seems to be an issue (?).

Note: Tested the same scenario in Windows, Android and Linux OS and I was able to see separate EuroLatin(SIL) keyboards for French and German.

I have attached the Screenshots for reference.
