As I've understood and learnt from both Norsk and deutsch, such parts of the words, like what you mentioned (an N coming after a L) are pronounced through the throat, so it might not be clear to hear for the auditor But, the speaker does pronounce it. You have to try on making sounds from different parts of your mouth and throat ! I recommend you to start with making a "mmmm" or "nnnnn" sound with closed mouth so you'd know which parts you need to engage.
Katten er på stolen = The cat is on the chair. Katten ligger på stolen. = The cat is lying on the chair. In both cases the cat is on the chair, in one case the cat is not standing, nor sitting on this chair :D That is from a Norwegian point of view. It took me a while to get used to DL's version of language. Sometimes one just have to choose the answer that come closest to "normal understanding". Here the point probably is where to find the cat, never mind what it is doing there.
