Products change to 'Sold out' as soon as a different variant is selected

[Robyn]

Can anyone help? All my products look as though they are available, but as soon as an alternative variant is selected (in this case, Size: A3, A4 or A5), every variant shows as Sold Out.

Shopify help have said they cannot help because I have amended the code. The only code I have amended is removing code so that 'usually ships within 24 hours' is not displayed.

I don't think it is an issue with Locations - I have only 1 location. I've tried having everything in stock, turning most product to 'not tracked', and also selecting 'continue selling when out of stock'. None of this makes any difference.

I am not sure if I am able to reply to comments. Just in case, my url is www.robyncaleyillustration.com, and an example product page where this issue occurs is Bedford Blues rugby club, Bedford | PRINT – Robyn Caley Illustration

Any suggestions would be extremely gratefully received, my website cannot launch without fixing this.

Thank you!
