Scaler shifts all notes

Hi im using scaler 3 with midi output to other plugin and disabling vanila scaler synth (not using any third party plugins just standard fl VST wrapper settings) and while making chord progression at absolute random moment it shifts notes for output plugin -2 semitones for some reasons. Removing scaler temporarily and project reload helps, but it sucks, it happens no matter what plugin im using zenology, serum, or even sakura
