Did this end up getting fixed for you? We ended up doing a bunch of EDI setup ourselves for Odoo. Some fun was with mapping shipping methods - trading partners seem to use a combination of fields to define it. We ended up doing settings for delivery methods to allow mapping on multiple EDI fields, the first screenshots here shows the mapping config https://steersman.works/a/71-odoo-edi-integration-and-configuration-by-steersman   Do you deal with it on EDI VAN side, or map in Odoo or something else? Though EDI is supposed to be a general standard, but it looks like each trading partner uses it slightly differently, maybe that just in USA though and better in EU... lots of fun :)
