Pc mfs 2024 basic training lessons: can't pass cabin flight controls

Hi all, I’m back to basic training sections. Have passed all of them till takeoff/landing except the section “Flight Controls”. Follow all the voice instructions steps and arrive to the last one: verify engine rpm indicator activity. What am I supposed to do there? I see the rpm indicator top left multifunctional display, it is highlighted in a blue square, I go up/down with gas and it give the rpm’s activity. Then what ? The instructor voice doesn’t give further instruction and I’m waiting what’s next, nothing move. The mission text assistance tells "check the rpm indicator by SHIFT+K , SHIFT+I , SHIFT+J , SHIFT+L " and I do it, but still nothing happens. Do you know what to do for the training session to end?

Thank you all
