I have just tried this all again.

Which step?
There are a total of 2 steps
Step 1. Export .csv report to hard drive and save
Step 2. Import .csv report to Cointracking
All completed within 2 minutes.
Same problems as reported to you before so which step is wrong???

I exported the report in CSV Extended view to my laptop.
I then re imported the same file into my Practice account via the Enter Coins page CSV and Excel import tools and compared the resultant entries with the original entries still in my Personal account and the bad news is that they are not identical.

The re import transfers all the correct existing data from the Comments column into the Group column, inserts a random date into the Comments column, deletes all the listings of exchanges under the Exchange column and removes all the entries under both the Fee and Currency columns?
You can see this for yourself in my Practice account.
Why is this happening when it is the same file(s) re imported that was exported moments earlier?
Obviously this messes all reports up and is useless to rely on for backup locally.
Please advise on how to fix this here openly on this forum as from experience things seem to get lost in the Help Desk.
Thank you
