Hi Steven looking very nice.
Juvenile foliage is caused by multiple things, lack of health, poor positioning, incorrect pruning etc. By the look of it id say it is sprouting juvenile foliage because it has either been pinches too much, or pruned too much. Have you been pinching all the foliage back, as in taking all the green foliage and pinching or have you been cutting extensions as they grow out? With scale foliage junipers you should only cut back extensions of growth, as in the dominant tip that extends out and cut back to another tip down lower.
To remove it you should wait for extensions to revert back to scale foliage which will appear from the juvenile. Once this happens you can prune as normal (cut extensions back to 25-50% in length and also remove juvenile growth by 50%. You must remove it in stages or else it will revert back again so cut 50% the first time and then if you prune again that season remove 25% of whats left and then the following year remove the rest.
