Problem with tracker window

I can see just options to select which kind of tracking I would like to use but no more option for tracking, Please where is problem ?

once again the stacked panel group feature bites users in the a@@. this is not your fault but Ae's faulty interface design. you are using what is called a stacked panel group. this stacks the group in such a way that can hide the panels boundaries if they are not selected.

if you click on the panel you can see it.

but if you are not selecting it, it could look like this:

if you take your mouse cursor to the bottom of the panel

you will see it changes to a moving boundary symbol. something like this.

now you can drag it down.

or maybe do yourself a favor and uncheck this feature option by right clicking any panel option of any panel and in panel group setting uncheck the stacked panel group.
