It’s ujpest I got confused with! They seem to have a different name every year.
Újpest have been called Újpest since they were formed in 1885, apart from a short period 1950-1956 when under communist rule they had an enforced name change to Bp. Dózsa SE (Budapesti Dózsa Sport Egyesület). After the 1956 revolution the name reverted back to being Újpest.
