I played a bit with the sub and I suggest Genopro to adjust the following narrative when:

1) “Unknown/Don’t know” option as been selected:

I suggest:

His unknown final body disposition was in …

or, if no mention of any date nor place:

His final body disposition is unknown. Or maybe no narrative at all?

2) “Other” option has been selected:

No suggestion. Up to Genopro.

3) “Body never found” option has been selected:

In this example, the narrative looks a bit strange/odd when other data (funeral, dates and places) have been input!
