By default lower level items are done first in lessons. You should always see vocab from a previous level before the kanji for a new level. If your current level is N, it goes:
Vocab for level N - 1Radicals for level NKanji for level NVocab for level N
With all that said, new items were added today across all different levels. But based on what you’re describing I don’t think it’s related. The newly added vocab items are all based on also newly added kanji items, so none of those vocab lessons should have shown up for you yet.
If my explanation above doesn’t make sense, or you’re seeing something that contradicts it, please post the specific items you are seeing lessons for.
