Zwift mobile app: event filter

Hi, filtering events based on event category is great option. I would like to have the option to select only a certain category (e.g. B category events for instance). Right now on iOS, if you click on B category, it will grey out A category option; still it will display all other events that are in category C, D, E - which makes it difficult to select B category events in the long list …

Thanks for all updates and keep going.
