EcoFlow Delta Pro 3 Hub glitch?

I have 2 Delta Pro 3 connected to a 240v Hub. For the past 3 weeks I’ve been off grid running my house, I had one of the DP3s connected to the AC outlet on purpose so that when I go back on grid it will charge the DP3, well for some reason it was doing AC pass through on the hub, I went to my garage to see what was going on and the DP3 that was connected to the ac outlet was charging but not giving power to my house, the other DP3 was doing all the work. So I thought maybe this was an update to the software that it would do AC pass through on the Hub but it’s say specifically AC pass through will be deactivated one hub is connected. This would be a excellent software update to do AC pass through were you can use an external gas generator to power up your batteries to have continuous power when there is no sun or use another brand of solar battery power to charge up your batteries while continuing to power your home none stop
