We are getting below error in our Kibana logs 8.7.1 and Elasticsearch version is also same 8.7.1  
why ECS version is 8.6.0 ? is it ok , if wrong how we can correct it?

```auto
{"service":{"node":{"roles":["background_tasks","ui"]}},"ecs":{"version":"8.6.0"},"@timestamp":"2023-07-17T04:19:51.452-04:00","message":"Error performing search in RuleDataClient - search_phase_execution_exception\n\tCaused by:\n\t\tillegal_argument_exception: collapse is not supported for the field [kibana.alert.uuid] of the type [text]\n\tRoot causes:\n\t\tillegal_argument_exception: collapse is not supported for the field [kibana.alert.uuid] of the type [text]","log":{"level":"ERROR","logger":"plugins.ruleRegistry"},"process":{"pid":50191},"trace":{"id":"2b2e83330722f2c1258e4b990d5595e4"},"transaction":{"id":"c5f4a76587ba2be3"}}

If you recreate any already created rules, does the error persist?
