I just noticed this now today (Jan. 25th, 2019) when I created a new roblox studio file that the labels in the Toolbox are not showing the right values, instead showing programmer-like identifiers.
This seems like it was like this since the previous update.
This occurs 100% of the time on a Windows 10 device on Studio version 0. 369. 1. 273919, when opening a baseplate or any other place.
