Mysql truncates the data - mysql

Question

I can't upload data to mysql with csv upload.
I got this error now:
It says duplicate entry for '7'. but it is not 7 actually. it is 907 in the csv file I'm trying to upload. Mysql takes only 7 of 907 for some reason. How can i solve this problem? please. thanks.
