ZIP+file name using two digits surrounded by brackets=error

I got a weird bug when trying to zip files with such names:
[01].png
[02].png
....
DOpus (version 10.2.0.0.4645) just ignores those files when compressing

It works if I add one more digit inside the brackets (or if I remove one digit also):
[001].png
[002].png
...

Now, if I am adding to an existing ZIP archive a file with the first kind of name, DOpus will just ignore it. But trying previously to add this file has corrupted the archive as I get the following message after trying to add a file with a "normal" name.

Structure error in ZIP file. The file may be corrupt. (ZIP error 3)[/quote]

Confirmed! We'll look into it.
