Tags such as “woo order” are not really intended for frontend use, and you could hide them using the columns argument of the transactions shortcode. But the filter is there so you can do whatever you want with the data. This includes using translations if you like to overwrite the tags and/or comments.

The comments can be configured in the payment gateway settings (see under “Comment template”). The default string is translatable. Other than that, you’d be better off overwriting the data on output using the filter.

Please let me know if you encounter any difficulties.
