This is just a minor issue. Above the reactions on a page, there is a box to choose what moderated level of reactions to show from. If I select ‘Show Reactions from Level 0’, the page refreshes, but with what ever previous value was in this list box.
Example: If the box shows ‘Show reactions from level 2’ and I select ‘Show reactions from level 0’. The page will reappear, but the box will have retured back to ‘Show reactions from level 2’. All other values -2, -1, 1 and 2 work fine.
