I cannot export GDSII after a merging a Gerber layer using Tools > Polygon Utilities > Merge Overlapping Objects.

GDSII doesn't support composite layers (i.e. polygons with holes/islands).  So what you have to do is link the holes & islands into the polygons.  You will need to link the holes/islands by using the feature called "Flatten Composite".  It is located in the menu: Tools | Composite Layers | Flatten Composites... 

The composite warning message (during GDSII export) will tell you the Job & Layer number where the composite is located.  Make the job active (menu: Windows | Workspace Browser...), and then goto menu: Tools | Composite Layers | Flatten Composites... 

This will flatten the composite (essentially link the holes & islands).
