about map and multi-location

I have two question.
1. about choosing multi-location switcher.
I registered 2 sample places in korea – Seoul and Busan.
When I use location switcher and select Seoul, the map is not showing Seoul. it just show Seoul and Busan all together in the main page map. I think it’s not changed from ‘everywhere’ to ‘Seoul’
Even I choose new york it just show same result instead of “no result found message” which i saw in demo.

2.about searching and setting address
for example, when I search ‘daejeon station’ in add place I can use auto-complete function but after I choose that address, it suddenly disapeared.
and region as well. but sometimes it’s working properly. I don’t know why.

How can I solve these 2 problems? plz answer me ~
thank you
