Every time I save my plugin options it erases another plugin options

I created two plugins, when I save one settings it completely erases the settings from the other one, and it also happens the other way round.

I really don't understand what the issue might be about since they don't share the same general configuration: one plugin options are saved in pl_popup_options and the other in pl_analytics_options. Yet when I update the first one, it erases the value of the other from the database.

Anybody faced a similar issue? What could be the reason for this?

Plugin 1

/**
 * Add options page
 */
public function add_plugin_page()
{
    // This page will be under "Settings"
    add_options_page(
        'Settings Admin', 
        'Pranalog Popup', 
        'manage_options', 
        'pl_popup_options', 
        array( $this, 'create_admin_page' )
    );
}

Plugin 2

/**
 * Add options page
 */
public function add_plugin_page()
{
    // This page will be under "Settings"
    add_options_page(
        'Settings Admin', 
        'Pranalog Analytics', 
        'manage_options', 
        'pl_analytics_options', 
        array( $this, 'create_admin_page' )
    );
}
