rspamd_init_filters: requested unknown module rbl

I noticed that some of SPAM emails are not rejected by rspamd and find their way into my INBOX. When I scan message contents using rspamd web interface, I get the following results indicating total score of 17.05, which would be considered SPAM by a long margin:

DBL_SPAM (6.5) [blablabla.xyz:url]
ABUSE_SURBL (5.5) [blablabla.xyz:url]
BAYES_SPAM (5.1) [100.00%]
PREVIOUSLY_DELIVERED (-2) [my@emaildomain.com]

MIME_HTML_ONLY (0.2)
ZERO_FONT (0.1) [1]
RCVD_NO_TLS_LAST (0.1)

FROM_EQ_ENVFROM (0)
R_DKIM_NA (0)
MIME_TRACE (0) [0:~]
RCVD_COUNT_TWO (0) [2]
MID_RHS_MATCH_FROM (0)

Score: 17.05 / 14

However, when I get that same message in my INBOX, I see the following in message headers:

X-Spamd-Result: default: False [5.25 / 14.00];
     ARC_NA(0.00)[];
     BAYES_SPAM(5.10)[100.00%];
     R_SPF_ALLOW(-0.20)[+a];
     FROM_HAS_DN(0.00)[];
     ZERO_FONT(0.10)[1];
     PRECEDENCE_BULK(0.00)[];
     TO_DN_NONE(0.00)[];
     DMARC_NA(0.00)[blablabla.xyz];
     RCPT_COUNT_ONE(0.00)[1];
     MANY_INVISIBLE_PARTS(0.05)[1];
     TO_MATCH_ENVRCPT_ALL(0.00)[];
     MIME_HTML_ONLY(0.20)[];
     RCVD_COUNT_ZERO(0.00)[0];
     FROM_EQ_ENVFROM(0.00)[];
     R_DKIM_NA(0.00)[];
     MIME_TRACE(0.00)[0:~];
     ASN(0.00)[asn:46573, ipnet:XX.XX.XX.0/24, country:US];
     MID_RHS_MATCH_FROM(0.00)[]

Seems like some of the rules don't apply here, like DBL_SPAM or ABUSE_SURBL. Are they not enabled by default? I tried adding "rbl" module to options.inc:

filters = "chartable,dkim,rbl,regexp,fuzzy_check";

But then I get an error in rspamd.log:

2021-03-08 13:48:57 #436504(main) <red3uk>; cfg; rspamd_init_filters: requested unknown module rbl

Am I doing anything wrong?
