I try to set and in and out point for a particular clip I want from the source like in the photo.
When I want to add a different part from what I originally did, then it only lets me change the in/out points for that clip from the source I already put using those points, and I cannot set different points and add another.
How do i add multiple clips from the same source footage to the timeline?
If you're double clicking the clip from the timeline then it loads that instance of the clip into the source and if you make a change to the in – outs on that instance, it'll change the clip in the timeline.
Double click the clip from the project window – bin to load it into the source monitor.
Make your marks, edit it into the timeline.
Click on the source window again and make new marks, edit into timeline.
