Prerequisites

• I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• The issue still exists against the latest master branch of bootstrap-fileinput.
• This is not an usage question. I confirm having read the plugin documentation and demos.
• This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• I have attempted to find the simplest possible steps to reproduce the issue.
• I have included a failing test as a pull request (Optional).

Steps to reproduce the issue

1.Multiple file uploading
2.Add 2 proper or valid file and 2 invalid file like jpg image convert direct in png

{"error":"File not valid, Please try another file","errorkeys":[1,3]}
4 second time same action we do and response return is below
{"error":"File not valid, Please try another file","errorkeys":[0,1]}

Expected behavior and actual behavior

I was expecting return same response like we visit 1 time
