Ran into an issue with products with Production Options that started with a number.
Steps to reproduce
1. Create new Option Template
- Option Field Type: Select From List
- SKU Contributor: Yes
2. Add two values
- Name: 1 - 2 Vacancies Per Month, Key: 1-2-vacancies-per-month
- Name: 3 - 4 Vacancies Per Month, Key: 3-4-vacancies-per-month
3. Create product using that option, and generate all SKUs
4. Browse to Product in store front and try to add to cart.
Expected result: Product added to cart
Actual Result: Product not added to cart and red error message box appears. There is no text in the error. There are errors in log.
