Error in Data Import Tool while uploading Lead

I downloaded the Lead with data and just made changes to the Organisation and uploaded the same file again but I am getting the folllowing error. Is it a Bug in the system or am I missing something.
Error for row (#24) “LEAD-00131” : can’t compare datetime.datetime to str


can you please share the browser’s console traceback ?

Thanks, Makarand
