Unless you cannot compress the ring once it is on the piston, the expander should be working fine (unless boxed incorrectly) - it should provide resistance to compressing
Did you clean the piston grooves out well? How well?

I soaked the piston in solvent and cleaned all carbon out. I suspect it is boxed wrongly as the instructions has diagrams, one with expander, one without. The depth of the oil rings differ between the with and the without. There is no way I can put the expander behind the ring and put it back into cylinder.
