Scaler 2.5 on Logic: latency wen changing instrument

Hey there,
I´m on Monterey with Logic 10.7.1 and Scaler 2.5.
When I use Scaler as an instrument or as a midi fx there is a latency which vanished when I clean the instrument/midi fx channel and reassign Scaler to the channel. Weird. Any idea? Is it probably a logic failure?
