This bug has occurred from the Chinese localization took place in Studio, however there are only few words were translated before which were not annoying to me so I did not treat it as a problem.
But today, most of the words in Studio were translated into Chinese. Because of the language difference between China and Hong Kong, I cannot understand some of the words in Studio so I decided to change the language back to English and I found that there is no any buttons in Studio that can change the language, the language settings in Roblox website was English already but this doesn’t help.
Here is my settings in Roblox:
Roblox version: 0.387.0.306142
System spec: Lenovo Windows 7 PC (64 bit), Pentium® Dual-Core CPU E5700@3.00GHz
