known issue Commerce bug: custom field gets wrong value

[opentype]

I have a custom field with numerical values:

Looks fine in the database:

Looks fine on the product page:

But once the product is put into the cart, the product in the cart will always use the next value in the set and continue to use the false value throughout the checkout. 
If I select “1" on the product page, the cart says “2”. 
If I select “2“ on the product page, the cart says “3” and so on. 

You can easily replicate it as a guest on my site. It happens for all products which use this field.

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.

I have taken a look at this, and its not actually showing a different item in the cart than when selecting on this end. Is this what you are referring to?

Please try it out on my website with the field shown in the screenshot (“Number of Desktop users”). The wrong value is added to the cart and persists throughout the purchase.

Have added some notes. This is happening only if you add a number there. As a temporary workaround, if you add some text in there, these will select correctly.
