Need help with the filename

[Troll180]

EDIT : Ok, I'm gonna flog myself as just restarting everything and I guess closing notepad+ before lauching the scraper made it work, I'm still curious about the 2nd point tho

Hi, so I tried to change the filename line in the config.json as :
"filename_format": "{date}-{filename}.{ext}",
in order to have a file named "27-08-2021-Name.jpg" but when I start to download pictures, all files are named just as I did nothing, just as {filename}.{ext} .
I'm using the last version (7.4.1) and changed the line for both Onlyfans and AVN.
Am I doing something wrong? Probably, can you help me? Probably :D

2. -> Also heard it was possible to rename the files already downloaded (with OFRenamer?) How that work?
   Thanks.
