ISM policy doens't apply

In out production cluster based on opendistro [1.13.2] we have multiple Index Management Index Policies with ism_template defined field, where we declare index_patterns. For example

        "ism_template": {
            "index_patterns": [
            "priority": 10,
            "last_updated_time": 1626953706345

this policy must be applied to any newly created index, that doesn’t match index patterns in other index policies, but nothing happens, and to that indexes doens’t have any policy applied

On test stand where configured much less index policies - all working, but in production does not, but in production cluster we have only about 20 policies

How this can be, and how we can solve this problem?
