I'm getting to use Concordance for the first time today. This is on L7 with indexing complete.
I'm attaching 3 images in the order in which I was working, with comments. Based on the UI, it looks like the Concordance is supposed to be a faceted style of experience; i.e. continue selecting options (part of speech, case, etc) to narrow what is being included in the results list. However, that is not the behavior I'm seeing.
Here's the first image, showing a baseline concordance results in the ESV of John. I've highlighted key things I was using and looking at.

Here's the second image, where I had clicked the part of speech "Adverb." Note that the number of adverbs matches the count in the first image, as expected; and the count of nouns has changed to 1. To me that implies that there is a single adverb which is functioning as a noun in John.

Here's the third image, in which I've selected "Noun." My expectation was that this would restrict the results to a single lemma, since the count was 1. However, the count of nouns goes back to the count in the first image; and the number of lemmas in the results list increased rather than decreased.

From this I conclude that either there is a bug in the Concordance feature or, more likely, the UI which implies a faceted behavior is not actually faceted. If it is the latter, then I really don't know what to expect when I click something. What did the count of 1 for nouns really represent, and why would I ever consider clicking it if it was just going to increase to its original count.
Can anyone help me out?
Thanks,
Donnie
