2.9.9b - Custom Field Type String - options not adding to the cart ( fixed in C)

[John2400]

  :DI have also added the new - update  - version (c?) - that did not fix my issue.

I also created a new test string and it did not add to the cart.

you can see that it does not add to the cart - and does not appear on the invoices either.

But because it does not recognise the string attributes then when I change a single attribute it just adds to the original. It needs to add as a new product to the cart. Same sku but different colours.

See images of my set ups.
