Hi

new verison without error when I place order.
It only generate the pure sequential order number without formatting.
such as {YYYY} of prefix

But the setting is disappearing {YYYY} prefix when the param saved

I have tried to fill in param of {YYYY} at prefix or sufix

at server log shown

thanks
