Google search console error: alternate page with proper canonical tag error

Hi there everyone,

I have recently got an error on my homepage which is stopping the most up to date version of it from being indexed - quite annoying!

The version of my homepage that is being indexed is www.baitboxvending.co.uk/ when the one that I require indexing is www.baitboxvending.co.uk/home. Googles indexing 'crawlers' are taking the former url as the canonical url, which means they essentially ignore the /home version. I don't even know where the www.baitboxvending.co.uk/ version came from as none of my pages on the squarespace editor have this url (as far as I can see, I'm no expert).

Just wondering if anyone else has this issue and knows how to fix it? 

Any help would be greatly appreciated :)

Best,

Leon
