Question about Smart Portfolio value and dividends

I'm very confused. I started my Stash account back in late-April, early-May. I set my Smart Portfolio to high risk and I've been putting small amounts into it weekly. It's paid dividends and I have the reinvest option turned on.

This next part is what is confusing me. After today all 4 of the ETF's in my Smart Portfolio are negative. Yet it's still saying that I have a small (about 1.5%) growth even though that account is actually down about $10 as of 20 minutes ago. It's showing a loss on the invested v. current value breakdown tab.

Do dividends reinvested not get tallied to your principal amount? As in does it only count money that I've actually invested, or is this just a glitch? I've been wondering this for the week and it's the only thing I can think of. Since dividends aren't really income I paid. So if I earned say $12 worth of dividends and my account is at a $10 loss, I'm still up because I technically haven't lost any of my 'paid' principle until that loss hits >$12?

This has been confusing me since I feel like I'm being given bad info by the app. Anyone have any experience with this?
