Subtitle not working in OS X 10.11.5

[dhyogo]

Hi, I tried transcode .mkv file (anime) with internal subtitle (.ass) but subtitle can't load.
Video load ... OK
Audio load ... OK
Subtitle ... No show

I appreciate everyone who can help me solve.

(UMS in Windows... Transcode same file with subtitle without problems).

Edit.:

[+ Info]

Using Video File Engine = [FFmpeg]
Accessing #--TRANSCODE--# folder and selecting 3rd option "Audio:AAC Subtitle: Portuguese"
Transcode loaded subtitle with success.
But with MEncoder engine sub. not loaded.

I'm already set *.* in Lang/Sub Priority but sub. load only that way.
