Has anyone experienced the error below about derive factors

We are receiving the following error message when trying to add in OE in our lower test environments.

We have validated they are active, have a valid assignment record, compensation record. We have not changed any of the derived factors. The only changes to OE we have made from previous is adding new plans. I was able to successfully add OE yesterday but today is when I am receiving this error message. Thank you in advance for any suggestions.
