Using Woocommerce 2.0.14, logged into the WP Admin area, I created an attribute (Product > Attribute) with three options/variations. Then I created a variable product and assigned those three options/variations (Variations, Add Variation). This all works fine, and my options/variations appear on the storefront for the product.
Then, in WP Admin, I added a fourth option/variation to the attribute (Product > Attribute) and tried to add this new option/variation to the product (Variations, Add Variation). The new option/variation I just added does not appear in the drop-down menu for the new variation.
I've tried refreshing the page, logging out of WP Admin and logging back in, and three different browsers.
I've thought about deleting all the variations on the product and then re-adding them, but I'm afraid if I do I might lose the three I already have assigned.
Has anyone else had this happen? If so, how did you resolve the problem?
