Vector file not actually vector: File #1578571038

Hello, recently licensed and downloaded this stock vector graphic - made sure I was downloading vector version, opened it up in Illustrator, but it appears to be an image. 

I've double checked to make sure it's not behind a clipping mask, but it's just a straight up image (see screenshot). The quality is also very obviously pixelated and not sharp/clear like vector should be. 

I tried clearing my cache, re-downloading 4 different times, downloading directly from license history - no luck. I've never had this problem before and am kind of stuck. Attaching original download for reference as well.

Any insight is greatly appreciated!
