task not completed ClearNavII

I am new to ClearNav2. I have planned and flown two FAI tasks using the ClearNav2. ClearNav gave me a start time and changed from the start to first way point and then to the second way point, and then to the finish but no finish was acknowledged. I had the same task in my Nano and my Oudie, both recorded a completed task and the Oudie gave me a "task finished" announcement. This sequence applies to both flights. When the flights were analyzed on SeeYou, the files from the Nano and Oudie produced task completed analysis while the files from the ClearNav in one case said no valid start and in the other only the start was acknowledged. Does ClearNavII give a task completed statement like the Oudie? This is very frustrating. Please help me figure out what I am doing wrong. I would be happy to email the flight files to anyone who is interested and could help.Thanks ,
