Managing shared hard drive on linksys e3000

I setup a shared hard drive on my Linksys E3000 and everything works fine except for this issue:

I created two shares, say Folder1 and Folder2. However any edits made to Folder1 from any laptop's File explorer (Windows & Mac) reflects on Folder2. If i create a folder in Folder1 it would automatically be created in Folder2 and vice versa. So it is like having just one folder. How can i edit these folders exclusively without having one folder update the other automatically.

Thanks
