Did you disable change addresses? The transactions show change addresses are not used....
This is not related to the issue of the OP.
Besides that, you can't 'disable' change addresses. That's how bitcoin works. You use one (or multiple) UTXO(s) and create one (or multiple) UTXO(s).
OP has send the whole UTXO 'to someone else', therefore it is a 1 input 1 output transaction.
OP, both of the transactions were received successfully.
Which tumbler did you use? And where did your second transaction go to? A private person or some business / website ?
If these are created by Electrum clearly something IS wrong, look at the transactions...
