phpMyAdmin Drop Query Affecting Dev DB and Live DB

I have two databases: one of which I’m using on a dev server and the other is the live version that I have exported from the dev database and imported to the live one.

I needed to go back and clear out the old dev database, and was going to import something else afterwards. I went and checked all the tables and did a DROP query, but for some reason, this dropped all the tables from both my dev database and the live database. Luckily, I had backups of everything, but could anyone tell me why this is happening?

Here is my query, which is created when I do a ‘Check All’ tables and select ‘DROP’.

DROP TABLE wp_commentmeta, wp_comments, wp_layerslider, wp_links, wp_options, wp_postmeta, wp_posts, wp_revslider_sliders, wp_revslider_slides, wp_slp_rep_query, wp_slp_rep_query_results, wp_store_locator, wp_terms, wp_term_relationships, wp_term_taxonomy, wp_usermeta, wp_users;
