some issues with Directory add-on

Hi,
there seems to be a few issues with the advanced search:
– download count >= XXX criterion has no effect
– reset button has no effect
This also means that when you have set a download date criterion, there is no way of removing it.
I have seen the above issues on both my config and the demo (http://demo.wpdownloadmanager.com/wpdmpro/advanced-search) .

Note: I have also posted this question on the Add-on page, but it’s pending on moderation.
