Hi,
I am sorry but "any save" is not precise enough to be able to understand your issue and reproduce it.
You could talk about the saving of the configuration like you can talk about saving of the taxes ; which are quite much different elements and do not use the same table or the same code.
Please provide a concret example with details about your configuration and the content you currently have.
Like : How many products, categories do you have ?
