PAYMENT ISSUE

Hi, I need your help. 

I was trying to find where I could ask for help and I think this is the right page to ask. 
I just got a bill from Paypal and I found out that it's weird that it charged twice.

I'm paying the monthly payment of the Adobe program's prescription.

When I was a student last year I paid 19.66 EUR, and now as a non-student, I pay 30.24 EUR. 

But what is this 60.49 EUR bill that I received and automatically they took it out from my bank account? 

Do you guys maybe have a similar problem or do I maybe forget something? I was just using the Adobe program every day. But this kind of bill that I got was the first time. 

What do I need to do? Do I need to call the Adobe service center? or Call Paypal? 
I really don't understand. 

Please someone could explain what's happening? 

Thank you.
