Can not upload a file under "upload1.path" on DO

Hello,

I’ve read this many times,

But the file is stored under the folder which is not expected. Is this a bug or am I wrong?

Btw, my configurations are below.

And these are the results.

How can I store this file like {{bucket}}/img/files/{{filename}} ?

Thanks,
