RPZ file

Version: 20.08.218
Release: 218

contains

button.blogs.yandex. CNAME . which is in the wrong format, it should be
button.blogs.yandex CNAME .

If used by unbound

rpz:
    name: "Extreme"
    url: https://block.energized.pro/extensions/xtreme/formats/rpz.txt

it produces:

error: RPZ: name of record to insert into RPZ is not a subdomain of the configured name of the RPZ zone

and unbound invalidates all entries from that RPZ that are listed past the wrong one. NLnetLabs/unbound#276 (comment)
