Welcome! Could you provide a full recreation script as described in [About the Elasticsearch category](https://discuss.elastic.co/t/about-the-elasticsearch-category/21). It will help to better understand what you are doing. Please, try to keep the example as simple as possible. A full reproduction script will help readers to understand, reproduce and if needed fix your problem. It will also most likely help to get a faster answer. --- _[View the full topic](https://discuss.elastic.co/t/object-mapping-categories-cant-be-changed-from-nested-to-non-nested/232591)._
