3d model - scene

[Greta]

I am trying to add a 3 model to Scene I did the following step

I created a multipatch feature in the place that I want to locate the model (recreation park)

Select the multipatch Edit>Create Feture> Add model (Collada)

Then the model appears in the right panel

The issue is when trying to add the model it keeps floating 

Could you please let me know what is wrong

Thanks
