Monitor Trigger Not Producing Alert (tests work fine)

[Bear-Up-A-Tree (M W)]

My company is using open stack 7.10.2 and I've been asked to set up a monitor, trigger, and alert for when a certain value falls below a set threshold. When I run the monitor, it works fine. When I run the trigger, it works fine. When I send a test message, it works fine. But, when left to it's own devices, nothing.
It did appear to work when using "define using visual graph", but I needed to use an extraction query to get the actual items I was looking for.

The extraction query (some redactions for security of course):

{
    "size": 10000,
    "query": {
        "bool": {
            "must": [
                {
                    "range": {
                        "<field name>": {
                            "from": 0,
                            "to": 11,
                            "include_lower": false,
                            "include_upper": false,
                            "boost": 1
                        }
                    }
                },
                {
                    "range": {
                        "Time": {
                            "from": "now-6h",
                            "to": "now",
                            "include_lower": true,
                            "include_upper": false,
                            "boost": 1
                        }
                    }
                },
                {
                    "match": {
                        "Name": {
                            "query": "<value>",
                            "operator": "OR",
                            "prefix_length": 0,
                            "max_expansions": 50,
                            "fuzzy_transpositions": true,
                            "lenient": false,
                            "zero_terms_query": "NONE",
                            "auto_generate_synonyms_phrase_query": true,
                            "boost": 1
                        }
                    }
                }
            ],
            "adjust_pure_negative": true,
            "boost": 1
        }
    },
    "aggregations": {
        "name": {
            "terms": {
                "field": "<field name>",
                "size": 10,
                "min_doc_count": 1,
                "shard_min_doc_count": 0,
                "show_term_doc_count_error": false,
                "order": [
                    {
                        "_count": "desc"
                    },
                    {
                        "_key": "asc"
                    }
                ]
            }
        }
    }
}

I've adjusted timing a few different ways between the monitor, trigger, and alert to no avail.
