Geopak Drainage Network Calculation Error

Hello guys:

I am having issues when trying to analyze networks in Geopak Drainage.  I get the following error when I try to analyze networks: Error Computing Hydraulics for Network (network Name), followed by: 

Errors Preclude Computations
Errors Preclude Computations
Error Computing Inlets Calculations for Network
Error in Inlet By Pass Designations - Loop Detected
Inlet Tñ( - Error Performing Inlet Computations
Drainage Area Tñ( Not Found

Any Ideas on what Tñ is? I do not have any nodes or areas named Tñ in my networks. When I check on my navigator, the Inlet tab is populated by a number of Tñs, see attached image. Any ideas on what's causing this issue and how it could be solved? I never had this problem with SS2. I am currently running SS4  Version (01.00.00), Microstation V8i (SELECTseries 3) Version, and Geopak V8i (SELECTseries 4) Version
