The function createPoolADD() supports the input of BNB, which it detects by checking token == address(0)
Later it calls _handleTransferIn(token, ...); with the original value of token, which can be 0.
However in the function _handleTransferIn() in poolFactory.sol there is no provision to transfer BNB (it doesnt check for _token == 0), so it will revert when you try to add BNB.
As a comparison, the function _handleTransferIn() of Router.sol does check for _token == address(0) and takes appropriate action.
Recommend applying the same function as _handleTransferIn of Router.sol to _handleTransferIn of poolFactory.sol. Better yet deduplicate the function by moving it to a library/included solidity file. Note:  There is also a  _handleTransferIn in Synth.sol which isnt used.
