Anti-tracker renewal not due yet, but automatic payment taken

I was sent an email to say my AVG anti-tracker renewal had been taken off at $49.99. I looked at the invoice from the link in the email and it does say it was taken out last on May 05 2019 for 1 year. When I looked into my subscriptions of which I have about four things, it see the next date was March 18th 2021, not March 18th 2020, which looks right by the invoice. 

I see, when looking into my subscriptions that I had a refund last year for this in June, I think, as they had charged me when I had already paid. I also see that this Anti-tracker was paid for within a bundle for  AVG Security/AVG Tune-up and AVG  VPN, with a total of  $196. something cents, that I forget just now. I think that was done in June last year and they all fall due in 2021. I've also got AVG Driver update, which might have been in the bundle, but I have paid separate for that I think. 

I don't understand, as I see that apart from the bundle payment, I have a separate payment last year for Anti-Tracker at $49.99c. I seem to be paying out more than once for this Anti-Tracker. Unless, they have either put the wrong date on this subscription for renewal or the invoice should have had 2yrs. I don't think I've ever taken this one out for 2yrs except in the bundle.

Something is definitely not right somewhere. I pay by PayPal. I've looked into that account for payments and it shows these Digital River payments or whatever they're called. It shows my payment that was refunded last year.
