Hi Castor!
The BGLs were returned from the bridge to address you specified. Checked txes, and indeed some of them were bridge 'payment to itself'.
Please don't use for now combined path like WBGL(Eth)->created BGL address->link this bridge owned address to WBGL(BSC)->WBGL(BSC)

This way of using is really creative by the way but let's keep simple single transfers for now (BGL->WBGL or WBGL->BGL)
