Prometheus alert multiple routes and receiver doesn't send one rules

I have this alert configuration and expect this behavior.

If destination: bloom and severity: info send to slack-alert-info - it's work

Error there. If destination: bloom and severity: warning|critical send to slack-alert-multi - this works with error. Sverity: warning sending as expected to both Slack's channels but critical sending only to default channel.

May someone help me understand my error, please?

Amtool gives no error.

Matching routes:
