Record type differs on Log a Call activity from initial creation

If your  default record type for the "log a call" task is the same as the record type you log the call with, the scheduled follow up task area will use this page layout and the task section will appear twice.

If the default record type is different from the record type you created the task with, the default record type will be used in the Schedule Follow Up task section. This is why the layout can differ from user to user based on their profiles.

You will have to change the default record type for the profile if you want every user to see the same layout for the Log A Call functionality.
