Uploading files goes to wrong destination when start other upload

Hi,

Firstly, thank you all for this nice and useful app.

That is a bug or what I think so...
When:
uploading 'files A' to 'directory A',
and start upload 'files B' to 'directory B';

Error:
in progress 'files A' uploads to 'directory B'

Expected:
in progress 'files A' uploads to 'directory A'
