Hello,
Concerning the first question, the reason you are not seeing those e-mail interactions is because you are looking at voice-only on that page. From the first image, if you look in the upper-right you can see the toggle for a specific media type (it's filtered for VOICE in the image). If you change that to EMAIL you will see the correct metrics.
Concerning the second question, by looking at the icons it appears that those are two inbound calls waiting (callbacks have the small arrow next to them). Without looking at the data specifically I could not say why those numbers are different. It might be worth filing a support ticket for more help if you are still seeing this issue.
