Not all words of sentences are being marked as seen (bug/feature?)

I posted this bug/feature(?) in the troubleshooting forum yesterday, but I have not gotten an answer and I was wondering if everybody else is also experiencing this problem. You can see the full description here: http://www.duolingo.com/comment/1463075 But I will also summarize it here:

Basically what I am experiencing is that when I train a sentence (e.g. "Det Schneider nimmt die Maße") and afterwards look in my vocabulary only some of the words are marked as seen recently (e.g. der, die and Maße) while others are left untrained (e.g. Schneider and nimmt).

Step to reproduce: (only for users of the old interface)

1 Run a timed practice session. Complete only one sentence and note it down.

2 Go to the vocabulary section immediately after. This is automatically sorted after which words were seen last, so should be easy to identify the words that were trained. Look for words that was last practiced "just now".

3 If you do not find a word from the sentence you can also search for it.

NB Some of the sentences are better marked than others, so it might take a couple of runs to get a sentence, which does not mark all words. In the German tree it seems like at least half of the sentences are not correctly marked.

What puzzles me the most is that words like der and die that are in almost every sentence are marked as seen, while a word like Schneider is not, even though I have only seen this word 6 times (Duolingo counting) and it has less than full strength.

I am very interested in hearing whether other users (of the German tree as well as the other trees) are also experiencing this. I would also be interested in hearing if anyone can come up with a possible explanation of how this might be a feature and not a bug.

I've noticed this in the French tree as well.
