I'm certain this is a browser issue.
Trying to execute a CSV Import and I have multiple pages of data and mapping files to choose from. Whenever I select a file not on the first page, it still uses the corresponding file on the first page.
For example, if I select the second file on the second page, it attempts an import using the second file on the first page. So, for some reason the pagination of both the CSV and XML sections of the UI don't appear to be updating properly.
Are there specific browser requirements to use CSV import? I've tried Firefox, Chrome, IE, Safari on Windows and Mac. No luck with any of them.
I assume you are using Csv import feature in Commerce Manager. Sounds like a bug to me. What version are you using?
