Bootstrap Nav Malfunction

I have monkeyed with the Results Display nav bar on this page: https://www.gopherstateevents.com/results/cc_rslts/cc_rslts.asp?meet_id=532&show_indiv=n&hide_team=n&hide_ind=n&sport=Cross-Country

Now when I make the screen smaller the "Results Display" is to the right of the list icon and when you click on it, it opens and closes immediately.  All I did was take the icons out of the links because I decided that they were not as descriptive as I had hoped.

Thanks!
