Preceding Bodies and 3D Features Disappear when in Edit Sketch

Hi Team,

I have an issue when I try to edit a sketch of one of the 3D extrusions, that all the previous Solid bodies and extrusions disappear. What makes it even stranger is that it only happens when I open edit sketch on one particular extrusion.

When I edit sketch in this extrusion, all preceding bodies remain

When I do it on this extrusion, all disappear

Does anyone know what could be causing this?
