SVG Icons way too large on import

Hi guys, 

I am working on a project and I have a lot of icons to import for use on my artboards. 

Some of them import fine and I can resize them how I like... but others are waaaaaay too big, even bigger than the viewport of the Adobe XD application is, therefore I cant zoom out all the way to click and drag the SVG icons back to size. 

I have also tried changing the size of the icons using the width and height specifiers, but doing this makes the icon just disappear from my artboards and I am unable to locate it. 

I have attached an image here showing what happens when I import the icon into the project, it is absolutely massive and takes up the whole screen... the black area is part of the icon lol. 

Please help, this is really holding me back from a project 😞 

Thanks in advance for your help!
