Hide unavailable variants in craft theme

[Cosydayscrochet]

Is it possible to hide unavailable variants with the Craft theme?

I had my shop built for me, but I'm struggling with this one issue mostly.

A lot of my items have two drop down options. One being type of item and the other a size guide. Different types of items need different sizes. You can see what I mean in this photo:

Is there a way to hide the 'unavailable' options? 

I've tried using the HiVar app but it doesn't seem to work

I have tried many a recommendation on this and it still isn't working so I'm wondering if I've uploaded my variants wrong?

I've grouped them by style then added the size variants that apply to each style. Is this incorrect? I'm really stumped and just want a smooth running and cohesive store.

Thanks
