CSV upload data issue

[hocngiap]

I usually saved all my data on a notepad in my car, and once a month i will key in all my data to my computer and uploaded to fuelly's server with "example-csv.csv".

usually it will add on the data which aren't duplicated. but after the 'major upgrade' on fuelly, i tried to upload my csv file and duplicated data were added into the system.

Could fuelly please have a look at this problem?
