Is DistroKid charging me $1 every time I upload a track?

Hi, I’m using DistroKid and I noticed that every time I upload a song, I’m getting charged about $1 on my payment method.

I thought DistroKid only requires an annual subscription fee and that uploads were supposed to be unlimited. But it looks like I’m being charged per upload, and I don’t understand why.

Does anyone know what this $1 charge is for?

Did I accidentally enable some add-on or extra feature?
