[Filters] Sigma Filters don't work in specific mutliple rules definition scenario

[sifex]

I noticed Sigma Filters don't work when multiple rule references are put upon them. No idea why yet.

Error: Error while conversion: Detection '_filt_icbtcxllye' not defined in detections in /.../sigma/rules/okta/okta_brute_force_followed_by_login.yml

Sigma CLI version: 1.0.3 (online pypi.org: 1.0.2)
