Received PayPal payment twice

I redeemed my SB for $50 on PayPal on March 4th. Received it within a couple minutes which I thought was really cool that they’ve got it on instant delivery.

But just now while watching tv, I received another $50 on my PayPal which I found weird cause I wasn’t expecting anymore. Looked in mine recent rewards, and only the 1 $50 is on there.

Anybody else having this issue. I thought maybe it could be because PayPal is on instant delivery now. Should I open a ticket?
