Custom Refinements React - Props not working

Hi, I’ve used the example of a custom refinement list in react as specified in the docs:

The refine results all display fine but the props you can feed in (show more limit, default refine) do not work at all. If i use the default refinementlist component they work fine but i specifically need to be able to customise parts of this list. Has anyone else ran into this issue?

Would provide code but it would just be me copying and pasting the example at the bottom of the docs link above.

Thanks,
Kev
