Duplicate entry in the macOS VPN menu in the menu bar

I have some VPNs configured on my mac. When I add a new VPN, things look normal i.e. there is a new item in the VPN menu on the menu bar.

However, after I connect to at least one of these VPNs, a duplicate entry always appears. In the image below, notice there are two "Disconnect [my VPN]" items in the menu, but they refer to the same VPN, and if I click either, both turn into "Connect [my VPN]".

I'm running macOS Catalina, but it's been there since at least Mojave.

Does someone know some explanation for this unexpected behaviour? Is there a way to solve it?

Solution 1:

I was able to temporarily remove the additional entry on Catalina by unclicking "Show VPN Status in Menu Bar", and re-enabling.

Will amend answer pending further research.
