Can you share your device's network configuration?
It sounds to me that you configured your devices to apply RPKI-ROV and
reject RPKI-invalid routes coming in via the blackhole BGP sessions, and
now are surprised that RPKI-invalid routes are rejected on the blackhole
You could configure your devices to not do RPKI-ROV on the blackhole BGP
sessions (essentially granting the blackhole BGP server unfiltered
access into your network), and continue to do RPKI-ROV on all other EBGP
sessions (transit, peering, private peering, customer facing).

Please keep an open mind that there might be a misunderstanding
