Metafields App - Can't Make Changes - Product Not Found

Good afternoon,

I’ve come back to the development of my site after a few months away, and I’m noticing a problem with the metafields app.

I originally wanted to change a value text, so I hit the edit (pencil) button, make the change and pressed update. I now see product not found underneath the product name in the app, and none of the changes are saved. I can’t delete them either.

I noticed in my metafields settings (in Shopify store) I have a metafield with a spelling error, that I don’t recall adding - thing is, I don’t remember adding this, and I can’t delete it. I think this is preventing me from making changes to metafields in the app and I’m struggling!

Can anyone help me here?

Cheers,

Lee
