When exporting a module to either XLS or XLSX format, we are seeing <div xmlns=http://www.w3.org/1999/xhtml> along with other HTML formatting tags on random artifact records. They are the same records every time but I do not see anything in the Primary text or any other attributes in the artifacts. My client has exported, manipulated in excel, and imported back into the module. I suspect there may be some excel formatting (since this doesn't happen with the CSV) but I can't confirm and wanted to know if anyone else has seen this and has a fix or work around.
