I did an automated install of a plugin (eShop Order Mailer) a single time, then activated and configured it, and it is working properly. Its folder appears only once in my wp-content/plugins directory, but it is listed three times in the Installed Plugins list in my Dashboard. It is listed twice with options Activate|Edit|Delete, and once with options Deactivate|Edit|Settings.
I would like to get rid of the first two instances that appear under Installed Plugins but am reluctant to click Delete on them lest it delete the active instance of the plugin.
Would appreciate some help on how to deal with this. I'm capable of manually editing the contents of the mySQL database without fear if that is required.
