You now have the situation where you do not sample *all items* belonging to a particular category in a given <block>. You have 6 items per category. In an "easy" block, you might sample 4 of them at random. Consequence: At the start of the next <block> there are 2 unsampled items left in the list. Those will be sampled first, then the list resets and *all six* items become available again for sampling, i.e., you might see repeats.
You ought to reset list.cat1items to list.cat6items /onblockbegin, just like you do with the main category list (<list categorylist>.
