Over 100% of production contracted to common market (Golden Rainbow)

I swear I posted this yesterday....but it's not here.....

Myy common market requires 20% of your production to be made available for contracts. The problem is that I have several corporations that have contracted well over 100% of their monthly production to various countries.

How does this happen? How can I make it so it doesn't happen again?

thanks

could you be more expecific?

Under the common market tab I offer contracts for products my corporations produce. I just go to the bottom and click confirm and it gives some kind of message like:
36 Contract Offers have been created.
4 Contract Offers have been canceled.
30 Offers were created because you commited 20% of your production to the Common Market.

But some of these have market commitments have increased to >20%. And some are well over 100%.

For example my corp KoTC JJE Stone (Jack Jones Enterprises) produces 30M stone each month, but somehow the contracted amount has increased to >60M stone. It has contracts for 203% of its production....

So of course half of the contracts are not being filled.

What is wrong with this system that allows this to happen? Or am I doing something wrong?

sometimes appear 200% or more cuz producting that product takes long time, or may be cuz you contrated more products that your corps produce. but this is a minor problem , there more things to take care of.
