Docx Services missing internationalization bundle for en_US

It fails to deploy.  When I noticed the missing en_US file I tried modifying the jar and adding en_US properties file but Appian rejected it as an unapproved plugin.  If it was on-prem it wouldn’t be an issue, but it’s cloud so it has to be approved.  I could go through the approval process but I’m pretty sure I would need to need to change the manifest because Appian isn’t going to like a different vendor creating a new version of an existing plugin without changing plugin name, key, vendor name…  Not to mention that the namespace, classnames and JAR name would still be the original vendor and that would take a little more work to change.

What is the best way to do that?  Other than “Synechron” - which is a huge global company - there are no contact links, developer names, email addresses on the AppMarket plugin page nor plugin documentation.  Appian community doesn’t seem to have a directory that I could use to look up Synechron developers that are on community.  I was trying to avoid going through a generic contact form on Synechron’s web site or random web searches for Synechron Appian developers.  If I open an Appian support ticket would they be able to give me contact information for the Appian developer that submitted the plugin for approval or would that be a waste of time?
