Keyframe copy

I want to use the same object in my timeline. In this instance a ball. But when I press F6 Toon Boom Harmony inserts a keyframe “without” the object.

It does this until I copy and paste the object to a frame on the outside say frame 60 then go back into the same timeline and F6 works just fine. What am I doing wrong? Or is this just a foible of the program?

First of all : Hi,

And…you are in the Toon Boom STUDIO forum not harmony…
