UnityADS does not load selected zone

hi to all,
iOS integration. My integration id is: "rewarded video" in set zone, but in logs always i can see "video" - why it loads wrong settings? in my settings Skipping is disabled, but i get ads with skipping buttons.

my code:

-(void) startUnityAds {
NSString *gameID = @"1031***";
[[UnityAds sharedInstance] startWithGameId:gameID andViewController:[CCDirector sharedDirector]];
[[UnityAds sharedInstance] setDelegate:self];
[[UnityAds sharedInstance] setZone"rewarded video"];
}
