Resetting Slide Layers to hidden

Hello -

I am working on an interaction in Storyline. The slide has the base layer, then depending on what character you choose, another layer is revealed.

If I choose to go back to this slide, whatever layer I was on when I left that slide is still revealed, plus the base layer.

I've tried "Reset to Initial State" on the base layer and additional layers but that didn't change anything.

Any suggestions?

Thanks!

Jenny
