Multisite error

We have wordpress multisite and we have activated the store locator plugin on a sub site.

There is a warning under User experience->map tab.Please check the screen shot.

And at bottom under map markers its written

Saved markers live here: /home/missionw/public_html/wp-content/blogs.dir/22/files/slp/saved-icons

I manually moved the icons to /home/missionw/public_html/wp-content/blogs.dir/22/files/slp/saved-icons/ but still this warning shows up

How to fix it?
