why do I now have two identical plugins, after new purchase?

I saw that my plugin Wocommerce Cart All in One, had expired so I bought a new on Envartomarcket. I saw there before I bought, that I still had 1 one year license, but I could not find it, so I bought a new one. I can now see that I have two. Can you see if that is a fault or if I have two can you then delete one? I only need one.

Thank you,

Anne
