[Layer not showing on Affinity]

Hello,

I downloaded an AI file from a vendor, opened it up in Affinity Designer and a layer is not showing (the "artwork" layer). On Adobe Illustrator it shows up because I had my friend open it with AI. I need this layer so that I can upload artwork for a vendor. I purchased this program to do simple packaging needs so need all the layers to show when I download vendor mechanicals.

Any support is very much appreciated.

 

Thanks!
