iOS bluewallet appears in BTCpay app

Hi. 2 days ago I have transferred btc into 3 different wallets of my iOS app, which is connected to my Umbrel server, non-custodial.

Today and surprisingly I found one of these 3 trx appear in BTCpay dashboard.
Have not used nor configured BTCpay, just installed out of curiosity.

Scary to me. How come? And why just one of 3?

Thanks in advance
