After upgradeing to AR 9.0 I exported the customer data because a number of current customers were showing up as inactive and I thought this would be the quickest way to fix it. I had used the export and import for changing tax groups for HST and it worked without a hitch. This time when I imported the data and number of the customer names were lost. That is the customer name is blank now. Any ideas what I did wrong or if it is a glitch how I can fix it other than going through and reentering the customer names manually.
