What does Reversal of ACH deposit mean?

[4screens]

I made a purchase of $149 on 11/15/16 and a few minutes later cancelled this transaction. When I reviewed my PayPal statement I could see both the payment and refund of $149 but I also noticed a "Reversal of ACH Deposit" in the same amount. Can someone in the community explain what the reversal is and did I receive a full refund?  Thak you.

Perhaps a reversal of funds that were coming from your bank account to pay for the puchase.

Thank you for your response!

A reference transaction noting that the funds were returned to your bank account.
