2013-14 Upper Deck Hockey Forum

I got myself back into the hobby last spring by buying a bunch of boxes of random hockey cards off of Facebook marketplace. Most of these were Upper Deck base from over the years. Since I've recently started actively trading here, I decided I should go through them all again and double check quantities and what not. 
In that process, I discovered that only one of the handful of Upper Deck 2013-14 cards I have had the foil embellishments around the name plate and the UD logo stamped on the front. 
The other six or so cards have no logo and the design around the name plate is just black. 
I can't find any listing for cards like this, here or on Cardboard Connection, Beckett, etc. Google takes me to some eBay listings for "no foil variants," but that's it. 
Can anyone explain what's up with these cards? Are they an unannounced parallel? Are they misprints? Did Upper Deck just forget to send a print run through the embossing press?

Just printing glitches. They missed the foiling step.  They won't be listed here.

Cheers. That's what I figured. Honestly surprised Google didn't take me to a forum thread of people complaining about the drop in QC at UD.
