Too high transaction fees - where is the problem?

Hey, I have a question about the transaction fee. Namely, I transferred the btc purchased on Binance to my private Ledger Nano S  several times this year. However, I was amazed by quite high transaction fees. I read the fee chart changes during the year but still my fees seem to be too high. I'll add that both btc addresses are segwit, which to my knowlege are more economical.

January 2020 :

June 2020:

Could somebody tell me why there are so big differences? The transfer amounts do not differ so much and have completely normal values.
