The :<number> just represents the number of times that size of structural has been placed onto your frame. In the past (like version 2013) it represent how many times that given component appeared in the frame or assembly.
If you want the browser and file name to be the same, when you place your member, select prompt for file name in the dialog and you will be prompted to change the name. Each memeber has to be done serparately and watch the location on the first member you change. It will not go to the normal sub-folder <frame assembly name>\Frame.
