Unable to add certain Unc Silver Eagles to sets 0

[GINO TUMMINIA]

Though the slots are there and Reg. Numbers verified, the sets are not accepting the 2018(W) Bullion, and 2018W Burnished coins from my Collection Manager. Message = INVALID ENTRY.

First verify the certificates on the NGC site.  Sometimes they have database errors and coins don't get into the database.
