Ef core rogue key autogeneration

I am lost, 3 hours down i can't seem to find why entity decides to create a insert on a autogenerated column. The list initiation is a ugly mess but its a temporary seeder to iron out the kinks of the schema. When i inspect the migration, the column has been marked with Identity, (1,1). I added the fluent api as a last resort. But at this point I'm clueless. print screens are partial, omitted for brevity, can send full if nessecary.
