Conflict between Product GTIN (EAN, UPC, ISBN) and SearchWP plugin

Hi,

We have SearchWP plugin installed on our website and when we search by SKU with a product that also have an EAN number set we get a 404 error.
If we remove the EAN number on the product, SearchWP return the correct product for the sku we search for.

Could you please tell us if you are aware of this issue and can help us finding a solution?

Thank you
