First thoughts: you are probably very fast-twitch with an under-developed aerobic system. And you probably ate before the test, perhaps even several hours before. If you were at 14 mM five minutes after a ramp test, then your peak lactate is probably much higher.
I used to have the same types of readings before my training volume was high enough to compensate for my FT bias. (My peak lactate after a sprint workout was 23. I would get similar readings to yours after ramp tests.)
Between 500-600 hours per year of training volume, I could still hit peak lactates in the 20s. It took a training volume in the mid-700s before lactate was reduced to the teens (in a peak test, not a ramp test). At that point, my baseline lactates were at or below 1.0. (And really, peak lactate may not have been reduced, just more absorbed by the aerobic system.)
In short, I suspect it’s normal for your physiology. (And I think most historical testing of endurance athletes is slow-twitch biased because that’s who’s drawn to the sports and most available for testing.) If you’re curious, do another test first thing in the morning before you eat (and before you get hungry). I suspect you’ll see a lower baseline.
