100%, ETA 0s, but it continues going higher

Trying to crack the password of a PDF file, and this is the current output:

username@apps:~$ pdfrip -f file.pdf default-query --max-length 4

The "175570000" number keeps getting higher, so I'm not sure if it's stuck in some weird loop, or if it's actually checking more characters than what it reported that it's checking. Here is my OS:

root@apps:~# cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"

And here is my rust info:

root@apps:~# rustup --version
