Sorry, there was no activity found. Please try a different filter. Buddypress/theme issue

I recently put together a site that uses Buddypress as a social area for users similar to Facebook by use of the Groups feature. However, when a user posts within a group the post disappears upon refreshing the page, all that displays is “Sorry, there was no activity found. Please try a different filter.” I think this may be a theme conflict as when I revert the theme to TwentyFifteen it shows the posts, but am unsure how to resolve this?
