Retina @2x Dropbox assets not coming thru on Codea 2.3.1

Is it just me, or the @2x assets from Dropbox are not coming thru anymore on Codea 2.3.1? I can’t sync any of the @2x PNG assets that are in my Apps/Codea folder on - when I sync my Dropbox assets inside Codea, I don’t see these items come thru in my Dropbox asset folder. I am using an iPad Air 2 with iOS 8.3. Anyone has this problem? Any solution?

Actually I found out that the @2x assets are synching, they are just not visible in the Codea Dropbox file / image viewer - so it’s a little hard to know if the files are indeed on the iPad
