Why are not all my 5GHz channels on my 60-series module "no IR" when having regulatory domain at WW?

When setting the 60 module to WorldWide mode all 5GHz channels are set to "no IR" - no Initiate Radio by default.
However when there are APs present that beacon on the 60s WW channles the "no IR" flag will be removed and does not show anymore when probing the module with "iw phy<X> info".

For example:
                       * 5260 MHz [52] (20.0 dBm) (no IR, radar detection)
versus
                       * 5260 MHz [52] (20.0 dBm) (radar detection)
