Hi Blake,
What version of CRM do you use? CRM 2013? Which rollup?
Do you mean the first time you import, it worked?
You can check the localizedlable, then search with the objectcolumnname, it should have two or rows with the same objectcolumname and languageid, then you can try to change the objectid of one from the old id to the new one which the label you
can see the translation in CRM, like english 1033.
It should be a workaround.
