Early versions of the UltraStudio 4K firmware did not support keying in 1080p50/60 resolutions. According to the Desktop Video release notes, this support was added in Desktop Video 10.9.5:

So you might try that specific Desktop Video version (just in case something about the keying support was broken in later releases).
Also, you will likely need to set the SDI output format to Single Link (rather than Dual Link) in the Desktop Video utility to make sure that it outputs 3G SDI over a single cable.
You could also try testing with the Blackmagic LiveKey utility (included with Desktop Video) to see if you get any different results than you do with QLab.
