Payment amount mismatch

When paying an invoice of 0.03346 BCH (amount embedded in QR), I sent this transaction instead:

There's clearly some subtle things that are off, perhaps in fee calculation, that sliced a sat off the final amount - and this broke the processor on the receiving site, which bugged me for "partial payment".
