Took me a while to find this on my own but in Node-Connections area of the Railing Settings, there is a drop down (circled in red) so that you can control the connection settings for the different horizontal elements of the railing. Make sure us you the right one selected and play around with the settings.
A word of caution though, I have found that every time you close the settings window it reverts back to the Toprail by default instead of the last one you were working on.
