Hi Rene - yes, we removed the micro kwizzes on lesson pages as they were not functioning correctly and causing other issues. We are aware that they were popular though and we're looking at getting them, or something similar, working again. You can add topics to you notebook(s) and kwiz against that/those in the meantime if you want to practise a single topic at a time (just put one or more lessons in the notebook using the add buttons and click test from your notebook). Every time you test against a notebook list you'll be given new questions from the available set, prioritised correctly by Kwizbot based on what he knows about your knowledge.
