I was invoiced to have a dual layer DVD R/W, but got PLDS DC-8a2sh? Do you know if this is Dual Layer capable?

Morning guys,

I came up with issue just now.
I was trying to burn a restore DVD and I wanted to save time and just get a DL DVD, while i looked it up, I realized DVD DL disc can only be burnt by a DL DVD burner.
And I went to check my invoice from Dell, it says 8X DVD+/-RW Dual Layer Drive,QuickSilver.
And then, my system info and another Hardware identification software said mine is PLDS DC-8A2SH.

I looked it up online, and it mentions nowhere that this is a DL capable DVD burner? Am I sent the wrong part?
