Wrong category

Some of my products are categorized as ‘’OTHER'' when I pull an excel export. However, on my profile, they are categorized as SILVER.

The below products should al be in the SILVER category.
 

Please advise of a solution as soon as possible. Thank you.

Usually the column after Grade is Collection.

Yes, it is strange. These coins are in your “Silver” collection so no idea why the exported excel file give them as “Other”.
