The row is deleted only when OPTIMIZE ... FINAL CLEANUP. This CLEANUP special keyword is not allowed by default unless allow_experimental_replacing_merge_with_cleanup MergeTree setting is enabled.

now it works only when changing settings manually

ALTER TABLE test MODIFY SETTING allow_experimental_replacing_merge_with_cleanup = 1;

@salisbury-espinosa you can set this as a merge_tree settings in the server config as a workaround.
