One Potential stage shows up twice in reporting due to extra space, not sure how to solve

Hello, 

We use the Zoho CRM Potential module to track jobs, and it's a very important part of what we do for tracking. For some reason, the Stage called "Generator - Appt Set" shows up twice. A second time, it appears an additional space is added. 

Stages Example below when I export to excel:

Completed and Invoiced 24
Completed, need to Invoice 1
Generator -  Schedule Inspection 16
Generator - Appt  Set 5
Generator - Appt Set 5
Generator - Deliver Generator 3
Generator - Need Pad and Permit 14
Generator - Need Proposal 1
Generator - Not Now 1
Generator - Quote Sent 260
Generator-Delayed Install 8
Need Proposal 4
Need to Schedule 5
Proposal/Price Quote sent 33
Service Scheduled 7
Work in Progress 3
Grand Total 390

The ones in bold are not duplicated, but for some reason they don't appear in a single line item with a qty of 10. Can you help us resolve this glitch? Thanks.
