Replica files on my original Dropbox because of Zoho.

Replica files on my original Dropbox because of Zoho.

I use Zoho on my work computer so I can edit, online, the dropbox docs from my lap top. My lap top has the original dropbox program connected to my C drive. 

I synced 3 dropbox folders to Zoho. Then, when I go back to my dropbox on my lap top, those 3 folders each have replica files of the other two folders. i.e. suppose each folder had 15 files each. Now each folder contains 45 files and all 3 folders hold the same 45 files. Effectively, syncing caused the the folders to merge.

I'm not sure if this is related to continuous sync vs one time sync. Or maybe there was some folder structure I was supposed to give Zoho and didn't know about it. On Zoho, no indication of the name for my original 3 folders exists. Zoho simply piles all the files from the 3 folders into one list and kicks a file to the top of the list each time you edited the most recent.
 

Any ideas? Thank you.
