Unexpected Load Activity Creation After Re-Dragging Process Operation

Hi Community,

I created a simulation scenario by properly defining the process operations. In the current setup, when I drag and drop X Operation, it is assigned under the Product Zone as a Transform Activity with both input and output defined.

However, if I delete the existing X operation and drag & drop it again, the system creates it as a Load Activity instead of a Transform Activity.

I am using the R2026x FD02 environment. Is there any setting that could be causing this behavior? 

Why does the activity type change after reassigning the operation? Could you please help me to fix this issue?
