The property 'X' on type 'Y' cannot be set because the collection is already set to an EntityCollection

I developed a database model with dotConnect FOR ORACLE and EF6. I did it with Version 8.4.303 and everything worked properly. I updated to Version 8.4.313 and after that my program no longer works.
I get an error when running : The property 'X' on type 'Y' cannot be set because the collection is already set to an EntityCollection.
All navigation properties of my model do not work but I have changed nothing.
This morning I updated to version 8.4.333 but I still have the same mistakes.

I use a DBCONTEXT with Devart ENTITY MODEL. Are the updates of dotConnect change an element of configuration or functionality ?

Thank you for your help

I solved the problem with the new verison V.8.4.333. I have update my model from database with this version and the problem disappear.
So the problem became with V.8.4.313 which is a bad version : burn it !

Thankx for the V8.4.333

We confirm that v8.4.313 generates incorrect code when the ProxyCreationEnabled property of the DbContext template is set to True (default value). The bug is fixed in v8.4.333.
