col-3 col-md-3
And that way it does not work
col-sm-3 col-md-3

Your answer is simpler than it sounds. You are using the classes of one version of the grid in the other. What I mean is that you are using the Grid classes of Bootstrap 4 in Bootstrap 3. It does not work.
The col-3 class does not exist in Bootstrap 3, so it does not work. You can replace with col-xs-3 I the smallest pro grid measure of BS3
Official documentation of the BS3 grid : link

So you see that in BS3 there is not only the class col-* as in BS4 does not have the class col-xs-*
col-3 col-md-3 works only on BS4
col-xs-3 col-md-3 works only on BS3
col-sm-3 col-md-3 works on BS3 and BS4
