I have reported this previously, but maybe I wasn't clear enough or didn't give you enough options. In the configuration section that relates to the formatting of filenames for downloaded files (i.e. Configuration ==> General ==> Downloads ==> Filename format for downloaded files"), you show as 1 of your options, "%res%.
The example shown, when this option is selected depicts the output filename would add a string as shown here:
04:05:00
However, that is impossible, because Windows won't let you use any of the following characters in file or folder names:
\ (backslash), / (forward slash), : (colon), * (asterisk),
