Marketing List is not appearing on Campaign Activity

Hi,

I am trying to associate marketing list with campaign and campaign activity. Here is my code:

 var addItemCampaignRequest = new AddItemCampaignRequest
        {
            CampaignId = Campaigns.FirstOrDefault(), // id of campaign entity
            EntityId = MarketingList,
            EntityName = "list" ,   //logical name of marketinglist
        };

        AddItemCampaignResponse addItemCampaignResponse = (AddItemCampaignResponse)_serviceProxy.Execute(addItemCampaignRequest);

And it is adding marketing list to campaign. But when i open the campaign activity marketing list doesn't appear.

This is campaign:

This Campaign Activity:

Version: 365 8.2 Onpremise

Do you have an idea?

Best Regards
