Netflix french subtitle

When I am watching a serie on netflix, i activate the french subtitle but they don’t appear. If I choose english subtitles, it works. Not that I can’t use the english sub, but for some series it helps to understand.

IS there something wrong with netflix or my setup has an issue?

Hello, since when are you having this problem, check if you have the latest firmware update installed (3.12.13). If you do have the latest firmware, try pressing the reset button on the bottom side of the WDTV. 

I did check the firmware is ok. I performed a reset, but no change, french subtitltes still missing. I also check on other platform and french subtitle are working well. Any idea of this issue?
