Can't see Server Connects, Browser, Query etc in content page

I gather I should be able to see all of the server connects, browser, queries etc from the main page in content pages but I can’t. So, for instance, I’m putting a new masonry component on my content page _trips.php. On my main page (index.php) I have a server connect sc_trip_blogs. When I go to choose the expression sc_trip_blogs (along with the rest of the ones in index.php) is not an option. Similarly, I can’t see the browser component on the dynamic events. Is there something I need to do to make those components show up? Thanks.
