[plugin: WP-Filebase] Adding " " into shortcode for FileURL

After I upgraded to WP 3.2.1, I have noticed that the plugin WP-Filebase is inserting “%20” in place of spaces in shortcode on my pages. This happens only when I select the FileURL tab (from the WP-Filebase icon just above the text editing box) — not with the Attachment, Single File, File List, or File Tree List tabs.

This was how it was done previously, which worked OK:

[wpfilebase tag=fileurl id=72]

But now it is doing this — not OK:

[wpfilebase%20tag=fileurl%20id=72]

Overall encoding for the WP site is UTF-8.

I have deactivated and reactivated WP-Filebase. It is the most recent version (0.2.9).

I have tried removing spaces from the actual file names that I want to link to. Makes no difference.

I can go into the HTML on the page and remove the %20 manually, but of course this is not how it is supposed to work.

Anyone have any ideas about how to repair or where I can start looking to locate the bug?

Thanks!
