I'm also under the impression it's not working as it should:

Oct 17 14:27:29 mail-cbf rspamd[56117]: <ac8e09>; neural; neural.lua:337: LONG:default:14 ann score: nan
Oct 17 14:27:29 mail-cbf rspamd[56117]: <ac8e09>; neural; neural.lua:337: SHORT:default:522 ann score: nan

Oct 17 14:27:29 mail-cbf rspamd[56117]: <ac8e09>; lua; neural.lua:455: cannot learn ANN SHORT:default: too many ham samples: 111

# fgrep -c "LONG:default: too many ham samples" /var/log/mail.log
10105
# fgrep -c "LONG:default: too many spam samples" /var/log/mail.log
1000

# fgrep -c "SHORT:default: too many ham samples" /var/log/mail.log
11536
# fgrep -c "SHORT:default: too many spam samples" /var/log/mail.log
2647

Maybe expiry is not working?
