GA: New user vs returning user

[![enter image description here][1]][1] The above is a screenshot from my GA account, behavior -> New vs Returning

What I don’t understand is why 114,875 appears to be the number of new visitors as well as the number of total users( or at least it seems to be). Sometimes it is 85.49% and sometimes it is 100%. It is totally confusing at the first glance. Why would google do this? [1]:
