Hi guys, do you have any glue for this issue?

The issue is there's a "type" mismatch. In the select drop-down, the options are in slug format, but the value stored in wp_wc_product_attribute_values is the integer value of the attribute. I am not sure which is the correct type. If I manually update the table via SQL to the slug value, everything works as expected and the options shows as selected in the UI, but that is only a hack until I can figure out the correct format.
