Presets doesn't stay selected

Hi,

when initiating sync I always have to select my preset again. Even if I click the red crossed button (see image) I always have to select again. Am I doing something wrong? Tnx, fusi.

That's as designed:

Also that's the reason why "Use same options next time" option is above the Transfer settings box.

Instead, change the default transfer settings in preferences:

tnx!
