Duplicate "check in here" messages in my timeline

I noticed that when I check in to my location, in my timeline I see duplicate check-ins mere seconds apart (I think). For the last week or so, my check-ins at home are doubled. What I think is happening is a UX bug: when I load my Placemarks page and "check in" for one, it logs a check-in. But then it automatically takes me to the location I clicked, with no visual confirmation that my check-in was already recorded. So I check-in again, which behaves the way I expect except it seems to log it twice (because of the no-message previous check-in).

I realize that now that I understand how it works, I could correct my behavior and only check in once. But I shouldn't have to. What you should do it make the Placemark page check-in link leave me on that page, and popup some other kind of confirmation message saying my check-in is complete. Change the button text or something. Taking me to my location page does nothing—I know the location, because I saved it to my placemarks. I don't need to see the page for it. Either leave me on Placemarks, or return me to my homepage with that checkin noted in my timeline.
