s50pro - setting the presets later, confuse the last state

There is a problem with s50 pro (i use my own m3u files for presets), if another stream (m3u) was saved later on one of the 6 presets, it will also ruin the state of the other preset after the save, I couldn’t figure out exactly what is happening yet, but in that case the solution is to re-store the presets from the first wrong state.
