Delete or Override is not working

Hello,
I used wpdownloadmanager and it was good. However, after searching for better solutions, I found your plugin. It feels better after I test it. However, when I upload the same file with the same name, it creates a duplicate, adding -1, -2, -3, etc. If the name of the file is the same, why can’t it override it? Alternatively, if this cannot be done, then when we delete a file, it should be removed from the uploaded folder, so we can upload the same file again. Although I deleted the file, I still see it there and cannot upload a file with the same name since it is creating a duplicate.

can you help me with this?

Regards
