Is there any way I can take my daily goal away? It's really annoying me because I can't see my progress to the next level.
Just set it to 1 and use one of the methods described here to see how many XP you have left until the next level. There are other ways too, but that one has a good roundup.
As for why you can't see it: you're in an A/B test. They're trying to find out how best to motivate and support learning.
