Umbrel + BlueWallet + LNDHub

Question if someone can help. I’m very new at this, but have managed to set up and fund my lightning wallet and fund channels. I set up the BlueWallet integration today, linked Blue Wallet HUB, and added funds to my personal BlueWallet Lightning Wallet via sending BTC from Cash App.

I do now see the funds in my BlueWallet app, but have noticed that the funds were also added to my Bitcoin wallet on the node itself. How does this work? doesnt that mean I can now spend those funds from my node’s bitcoin wallet, and if so, what happens to the duplicate lightning funds in blue wallet?

Confused. sorry if it’s a noob question.
