Search all sentences doesn't search my own collections

More often than not, Search all sentences doesn’t find matching sentences in my own collections, even though I know they are present. I have seen my own collections in the search results occasionally, but it’s very unreliable.

The following screenshot illustrates the problem. I know that I have both sentences in my “diverse” collection, but only the second is found by the search:

The difference? In the first sentence, my cloze word is “sea”, not the standard “solitario”. In the second, it’s the standard “tengan”.
