RFlink debug warnings filling the HA log. How to fix?

Guys,
I’ve noticed since I rebuilt my RPi 3’s HA software that I have a LOT of debug warning error messages every day from RFlink (which is working fine for the sensors attached to it). The HA rebuild and the noticing might be a coincidence.
I tried the self help route, this was the best advice around below. But it did not stop the logs being listed.
I added this to the config.yaml to try block those warning level logs and leave higher level ones, did I not get that syntax right ?


logger:
  default: warn
  logs:
    rflink: error
    homeassistant.components.rflink: error

A sample of a few of the errors in just over one hour.

These warnings come from rifling (it should show you that in logs btw like

2019-07-19 18:16:27 WARNING (MainThread) [rflink.protocol] dropping invalid data: 20;00;Internal Pullup on RF-in disabled

so you don’t need the second string.
I have this on 0.95.4 and it barely shows me anything, no such warnings:

default: warning
logs:
  rflink: warning # to see things like "Internal Pullup on RF-in disabled"
