If I give my vending machines a different name (default vending machines in outpost), it will still show the default names from the vanilla vending machines. 
I edited the name in the bottom right note as instructed.
Any idea how to get the names to display correctly?

I just tested and it's still working correctly for me. The only issue I noticed is that sometimes the name blanks out but comes back later, which I think is a client-side issue.

Hello @WhiteThunder,

I have the same issue as @MisterKiT1111.
The problem appeared two wipes ago (if I remind correctly).
The problem appeared on a Custom Map but also on a Procedural Map.
I will share my configuration/data files in a private message.

Regards, WouayNote.
