In finder left panel under Yosemite under 'shared' get multiple drive listing

When I click on 'Shared' in the left panel I see a list of my boot drives with a number in parentheses. For example I see "Gray Study Mac Pro (x) where there are thirty identical entries from (2 to (31). I see the same thing from my Mac Mini but cannot connect to my Mac Pro even though I have designated it shared.

Under 'Devices' There is a list of my Mac Pro's drives with Gray Study Mac Pro (32) then all the other drives.

Any ideas? Thanks,

Rich
