Any idea on what is causing this?

https://gyazo.com/c0c63d2a4d6fb7c23e267670570873b1 when i install the latest version off curse 7.0.8 it works fine, but when i tried the latest one this happens

Is now the error I get:

This is because you or one of your characters have the new dungeon keystone.

I'm not entirely sure if the abbreviations point to anything but I added my own and it appears to be working fine.

Working solution - add in savedisntances.lua

Add below line 64 [235] = L["SotT"],
add below line 80 ["Seat of the Triumvirate"] = L["SotT"],
