Anyone veteran PowerTap Joule 1.0 users out there?

During this off season, I have added power to my bike. I have a G3 hub paired with a Joule 1.0 computer and I am using the Power Agent software to analyze ride data.

Realizing that there is a lot to learn about training with power, I have spent the off season focusing only on learning how to train with power.

I still have some unanswered questions though...

1. While riding, when beginning an interval, I will hit the interval button. The "INT" shows on the Joule 1.0 screen. However, all the ride data (power, average power, normalized power etc.) showing on my Joule screen is still for the entire ride. Shouldn't it show just the data for the current interval while in "INT" mode?

2. What is the small triangular arrow that you can move around the screen of your Joule? It can be toggled around the joule screen next to the different ride data outputs.

3. When I upload my ride data into Power Agent, The intervals that I marked with my Joule during the ride does not show up automatically. I have to mark them manually within power agent. Shouldn't the intervals that I marked with my Joule during the ride show up in Power Agent automatically?

I have read all guides, reviews and searched all the forums I can find. For the life of me I cannot find the answers to these questions. Any help would be greatly appreciated!!
