Chart packs RNCs?

I recently purchased and updated the Caribbean chart pack. It seems these are only ENCs. I have enabled the raster icon and even when the vector icon is disabled, no RNC is evident. Is this correct?

Also, on some of the lights, what are the labels VQ and UQ? Does the 'Q' mean quick?

Yes Meltemus charts packs contain only ENCs.

Q means Quick indeed, VQ is Very Quick, and UQ is Ultra Quick
