TextRender component doesn't change text

iMac 12,2 AMD Radeon HD 6770M 512 MB. OSX 10.10.5. UE 4.9.1
TextRender component doesn’t change text even in text content entered new string and compiled.
To reproduce - just create new empty bluescript and add TextRender component, then try to change Text to any other text, but on screen (and in game) we could see only Text.
Here is my screen:

Only one solution I found - save and reopen bluescript
