Plugin is totally unresponsive

can anybody please help me stop this from happening?

As you can see from the image below, without the images my mobile menu looks great, however I want to have icons in front of the menu items.

In the picture below you will see what happens when I add the images using this plugin to the menu. It destroys my menu completely.

Can somebody please help me work this out as it is driving me insane, although this plugin is not responsive there has to be a work around, even if I have to disable the plugin for mobile view somehow. I’m desperate.

Thank you
