Double Billed - Squarespace Scheduling and Acuity?

Hi all ~ TIA for your wisdom & guidance

I'm am currently receiving 3 charges from Squarespace - 
1. my Website $29
2. for Scheduling $25

I am also getting billed by Acuity ~ 

Am I getting double billed for similar services? Isn't Acuity a part of Squarespace? 
Where can I find a description of what Squarespace Scheduling is/does?
I want to get more information - but it seems like one of these charges is not needed. 

Thoughts?
