term_order-field not copied to wp_x_terms when switching to multisite

Hi,
Switched a site (with WooCommerce) from stand-alone to WordPress Multisite and then added a few subsites into that setup.
Somehow the term_order-field isn’t “added” to the added wp_x_terms-table when creating a subsite (with x being the “site-identifier”). Not initially and not later on, when using the field in database-queries.
This results in the problem that you can’t add categories in WooCommerce in the subsites. When adding a category it LOOKS like it does, but after refreshing the Category-page the category is gone ?? I discovered database-query-errors that made me suspect this when switching on the debugging in WordPress.
As the term_order-field isn’t part of the standard setup and is added by your plugin I suspect that your plugin doesn’t check and correct the field-ommission when using this field?!
