I was told by support PM: Currently remove all the date from "post_date" means blank all the date, and then upload your csv file then your file will be imported in your database without any error, Currently it is not working in the latest version of "Wordpress" our technical team is looking for the issue, soon we will release the new version with problem solved. Now I have the job of removing 240+ DUPLICATE listings on my site!!!! This not only didn't work but provided me with hours of extra work when my site went live this week to the entire community! Sorry I was satisfied but today I'm VERY disappointed in this kind of 'solution'...
