Can I set only one Marketing Activity per Salesforce Object in the Salesforce App?

I am currently testing the Salesforce App.

We're testing Marketing Activity, and there's Marketing Activity with the Activity Type as Email Open and Activity Type with the Activity Type as Email click, of which data comes into Salesforce only for the first working Email Open.

Can Marketing Activity specify only one activity type in the Object?

I definitely checked that Campaign Members were created for Email Open, and I ran the Email Click test,

Activity Type is not entered as value for "Email Click".

Please tell me how I can send multiple activities to one campaign member as one customer may have multiple activities in one campaign.
