Apple charges me for the Family storage plan and my personal plan.

Hi, recently we switched with my family to 2TB family plan. I'm the organizer on that plan. For couple of months apple is charging me my 9,99euro for 2TB family plan and the 2,99euro for my previous 200GB plan. I was expecting that I will get charged only for the 9,99euros for 2TB. In settings under the manage storage I can see the storage bar of the 2TB and when I click the change storage plan it is selected the Icloud+ 5GB free. How should I keep only my family charges and avoid those 2,99euros?
