Language don't change instantly when clicking "Done"

One day i was going to change my language to Thai (ไทย (ประเทศไทย)) and it doesn't change when i click "Done", it was still English. It does affect all languages. It only happend when i Double-click it.

Steps to reproduce:

• Go to Options... > Languages
• Choose your wanted language
• Click "Done"
• See if theres a loading screen processing the change

Is there a way to fix it? If not, did i misread something in the bugfix patch notes? Let me know if you can help this, Thanks.
