Hi, @aurdipas! I'm taking a look to your report. I'll get back to you with what I find.

Hi again!

As we know, the split-select-multiples feature supports only static itemsets, but when a <select> or <select1> has a static itemset, but includes a predicate such as [some_field='some value'], it becomes a dynamic itemset.

At the moment, I can't provide a quick fix for this scenario, but I've filed an issue documenting this for when we have cycles to address it, or in case anyone wanting to help finds it :slight_smile:
