If your customer sent 0.0350349 BTC to 14JW3BCbe2CE4gBESSevpUqSwggUsxVfsT, the wallet probably sent the remaining balance to another address in his wallet(bc1qeda79n8et2s5nu6u8gqa5wvhaxj4tmj296xlje) aka change address.
As far as I'm aware, the only two wallets that support "bech32" (aka "bc1") addresses are Electrum and now (as of v0.16.0) Bitcoin Core...
- snip -Who initiated that transfer? And
what wallet were they sending from?
