Offhand I'm not certain what this is about! The only thought I can offer is to make sure that the metadata you used to generate the subxt types is from exactly the Polkadot binary that you are connecting to for your test.

@ascjones may well have a much better idea than me on the matter :)

It's probably because of #330.

You can try the commit before that PR to confirm. The fix we need to have it work for different versions of signed extensions is #331
