OJS 3.4: change files has some bug in submission workflow

Describe the issue or problem
env: ubuntu22.04
version: ojs3.4
I uploaded a wrong file “xxxxx.pdf”, then click the “change files” button to upload the correct file “yyyyy.pdf”, but both the “xxxxx.pdf” and “yyyyy.pdf” are all upload finally.

excuse me, is it a common problem with ojs3.4? I am really looking forward your help, thank you very much!

Hi @xiongfeiyan,

Did you submit the file prior to changing it?

Hi @rcgillis,
No, I didn’t submit. Before changing, I just uploaded it without any other events.
