When I run the following command I get two entries in our config for Elastic Search 7 and 5
php bin/magento config:show | grep -Ei 'elastic|system/full_page_cache/caching_application|varnish|catalog/search/engine'
catalog/search/elasticsearch7_server_hostname - serverhostname
catalog/search/elasticsearch7_server_port - 42630
catalog/search/elasticsearch7_index_prefix - magento2
catalog/search/elasticsearch7_enable_auth - 0
catalog/search/elasticsearch7_server_timeout - 15
**catalog/search/elasticsearch5_server_hostname - differentserverhostname**
Why is elasticsearch5 appearing and how can I remove this line. Everything on the admin side is set to Elastic Search 7.0+
