Slow and steady build -- it's online! Question on 2nd battery disappearing?

So I know this isn't going to have any juicy info or anything ground breaking, but I'm too excited to not share. Got all 6000xp and 2 EG4 indoor batteries about a week ago.

Slow and steady build, got them in place, got my PV wires run (but panels arent setup), all the heavy cabling done, battery comms, and got it online today successfully and everything appears be showing correctly.

As you can see from the screen shot -- it all looks great, however I noticed something perhaps 10 minutes later maybe someone could shed some light on:

I refreshed the page and it's now only showing 1 battery? Is this because I have zero loads connected to it by chance? or is there a specific port I have to plug the comms cable in? Both batteries have the green light on the front showing all normal/good.

Thanks in advance!

Update: adding to the weirdness - when I sign in on my phone to the monitoring portal, it does indeed show 2 batteries in parallel with the correct total capacity. (screen shot attached)

Thoughts on why the portal on my desktop PC only shows 1, but the phone app shows correct (2)?

Thanks!
