If I understand correctly, the conflict happens only on the dashboard pages? Can you please paste the following code in your theme functions.php file and see if the issues persist?
add_action( 'admin_enqueue_scripts', 'plugin_dequeue_scripts' );
function plugin_dequeue_scripts() {
$plugin_id = get_current_screen()->id;
if ( ( $plugin_id != 'settings_page_fp_foundation_assistant_settings' ) && ( $plugin_id != 'post' ) && ( $plugin_id != 'page' ) ) {
wp_dequeue_style('fp_foundation_assistant-admin');
wp_dequeue_style('fp_foundation_assistant-admin-rtl');
}
if ( $plugin_id != 'settings_page_fp_foundation_assistant_settings' ) {
wp_dequeue_script('fp_foundation_assistant-foundation-6');
}
}
The code removes the plugin’s styles and scripts from all pages except the plugin’s options and the new post/page.
I am currently testing the next plugin release, so I will include the fix in it if everything works fine.
