Cubase 12 some errors using ara (spectral layers & vocalign ultra)

I was Experiment 2 erros diferents using ARA recently.

1.- after using Spectral layer Pro in my track with ARA and “make Extension permanet” when I try move the size of event the Cubase stop working. bad bad.

2.- some times using Vocalign 4 Ultra the changes is no reflected. In the software all apparently works but the result is not applied.

(my english is bad I speak Spanish)

when you insert by error a “RANGE OF SILENCE” and “UNDO” the ARAs processing move internally the events… bad bad
