Don't worry about it - you have only had 4 lessons and violin playing is VERY hard.
It sounds as if you are slightly plucking the string as you release your finger. This may be due to the angle of the finger, angle of release, tension, sweaty finger.....a combination.
I still, after many years, occasionally do this in fast passage work across the strings, and it is always down to tension.
Your teacher will help you sort this out. There is more frustration for the adult learner because we know how it should sound, but on the other hand we are more motivated and can often make faster progress.
No kidding about the very hard part!! Every day I find new problems!!! Sometimes, some problems go away, and some days, they all appear on the same piece. It's very frustrating.
It must be my finger angle, because when I just stop the string an lift my finger, paying attention not to pluck it, it still rings... I'll show my teacher next week.
Papini's theme variation is driving me up the wall.
