Bullet Points Not Showing

I have an activity website that uses the Hotel Galaxy theme.

When I use bullet points in the editor they look fine but do not show up at all either in preview mode or when published. This applies to ‘dot’ type bullets (‘unordered list’ in the editor) as well as numbers. This problem occurs on every page of the site that has bullet points (a lot) but for ease of reference I have included a link to one page that should have both a numbered list and bullets. It applies to both desktop and mobile use.

On the example page, everything below “Stuff needed” should have a bullet point and everything below “instructions” should be a numbered list. It looks correct in the editor.

I have tried searching this forum for similar problems and copying suggested code into the additional CSS section but this didn’t work. I am a basic user – I can’t write code myself.

All help gratefully received!
