Unfortunately, based on the evidence you've provided. There is no way of us confirming or 'proving' that the bet was placed automatically. From my perspective, based solely off what I can see, it looks like it comes down to user error, and as such, this isn't something we can compensate you for.
That said, I can see the outcome of your second hand was voided after you chose to stand; as a result of that, you were kicked off the table. Due to this, I am happy to compensate you for this hand.
I've personally not heard of a dealer 'making you bet' before, so going forward, I'd advise only going up to the amount you are comfortable betting with - rather than going to the max. If you are confident that the bet was automatically placed, you're more than welcome to raise a bug report so devs can try diagnose the issue when available.
