We have used the same configuration but, we can see inclipboard that that the filename is encoded wrongly if there are characters like (,),& etc. also the parameter hiddenFilePath is blank in the clipboard. Upon searching in forum I found this article : SA-23777, which states that if the same section has a when rule for display condition then hiddenFilePath will be blank.
If that parameter is blank there is no way to get a rightly encoded filename.
