When I checked gracenote data guide for Poland the Free DTT or Poland Extended it associated complete random channels with those detected in HD Home Run. For those option I had to manually match the channels. But WP channel is missing, it is broadcasting on MUX-8 so it has to be in Gracenote, not sure if this is their fault or yours when importing.
Also, why so many option? There is no way to use channels in Poland other than terrestrial service. Freesat is nonexistent unless new government do something.
Free DTT is the same as "Local over the air broadcast" not sure why additional option "Polska" i "Polska rozszerzona" , you should delete all other options as there is no way to use paid-tv-operators (with probably exception Canal+)
Also some post-codes like 00-250 gives javascript error.
