How to remove underscore in the response headers?

Hello. Beka come with the headers for the file name.
When logau name, you get something like "filename.xlsx"but when you install the headers as filename, then the output is "_fileName.xlsx_"
Maybe it's not even that comes with Beck, maybe it's some other settings ?
Work through the Windows. Please tell me how to overcome the problem and remove these underscores.
