Bulk Rename Utility

I have hidden file "C:\Users\Hans\Pictures\Picasa\Exports\Picasa.ini", start BRU 2.7.1.3 64bit (Win7-64-Ult SP1) in that folder, filter "*Picasa.ini", "Hidden" active. Above file is listed as expected, but if I active "Subfolders" the file "disappears partly" (first line in 2. screen shot shows another ".picasa.ini" file and is then overwritten by data from original "Picasa.ini" file, expect name)!? If I rename the file to ".picasa.ini" everything is OK (same file does not disappear with this name, and you see that 4 files should be shown, not 3 as in 2. screen shot).
