AT result in Translation Results window is not properly displayed. (Sometimes throws errors)

In the Translation Results window, I'm experiencing errors ONLY with AT result from Language Cloud.

It fails to properly display the result retrieved from Language Cloud, (e.g. some charctars not displayed and substituted by a plain square or sometimes throws an error dialog). Even when it does display the result, it actually uses a different font (again, only AT result) from other result like the ones from TM. The font used by AT results is actually not following to any other font setting.

Any solution to get AT result properly displayed? (By the way, I'm using Studio for Japanese-English translation. This problem is happening when AT returns Japanese language result. The proper Japanese font is not chosen.) 

It seems the result string returned from Language Cloud is handled differently in Translation Results window, and the font setting for others is not applied. Because of this behavior, returned Japanese strings sometimes contain missing glyphs, which in turn are sometimes substituted by squares or other time throw a memory error.

I have contacted Language Cloud support and they identified this as a Studio problem, how it handles the returned strings...
