Hi Victoria,

Apologies for the trouble — that error was a bug on our side, not anything wrong with your data.

When you submitted the amendment, the form was passing an empty value for the prior accounting period dates, and the database was rejecting it with that SQLSTATE[22007] message. It blocked the entire save, which is why you kept hitting the same wall.

I deployed a fix earlier today. Please try submitting the amendment again — it should go through cleanly now.

If you do see the same error, post back here and I'll look at your filing session directly.
