Completion Type not working at end of module

I'm trying to end my module with the Continue Divider but ensuring Completion Type is Complete Block Directly Above/Complete All Block Above (to ensure the button above this is at least clicked on before they can finish) but the block above is not sticking as required. It's staying as just a normal Continue divider. 

I've tried adding spacers/blocks above and below to see if that would trigger it to be a completed required type but that's not doing it. Any suggestions would be great. Thank you!
