Are you saying that the action on the strings too high to your liking and they cause you diffulty to press, thus producing fret noise?
You can check it on your own,for classical guitar 4mm string height on the 12th fret from the bass side, and 3mm from the trebles side.You can lower to 3.6mm/2.8mm as you wished.Also use Normal Tension or Light Tension strings can help if it is a 65cm guitar.
