Moving from lastpass to bitwarden

Recently I have moved my password vault from laspass to yours. I have got through your website which indicates step by step how to move forward, however, not all the passwords on the cvs file have been imported. the file contain over 3000 login passwords and only 475 have been imported. And no error message come, only a message informing me that the import have been successfully made. would you please helped me with this issue

thanks

You will need to open the LastPass CSV file in a spreadsheet app to see how the data looks. LastPass might have a comma out of place?
