Wrong sync after editing a file

[sirio81]

Hi, I'm running btsync on my laptop (debian wheezy 64 bit) and I'm syncing 3 folder in total (Camera, Music, Lazy Geek).

These folder are synced on my android phone (4.2.2.).

Btsync is 1.2.9 on both devices.

 

I'm focusing on the folder "Lazy Geek".

It contains only 2 text file.

I tried to edit and save the secon text file from my laptop.

After few seconds, btsync start syncing.

What I see on my phone is that the file I've been editing disappear from "on device" section;

I can see it in "All files" section with the loading bar.

It stays there for several minutes.

Suddenly it appears back in "On device" but my changes to the file are lost.

Also on the laptop I have the old file version.

 

The clock difference may be of 2 deconds max.
