I'm not to sure even now if the 'Update preset' button is supposed to save scheme for the next time.
However, I became sure that this is an error when I tried to add a new preset and saw that it wasn't there on the preset selection drop box the next time I tried to organize files.
Steps to Reproduce:
1. Open organize file menu on any song in local collection
2. Try to change the scheme and hit add or update preset
3. Close the menu and open it again as if the step 1
The modified preset is gone
The preset persists
