Hello, Vu Ngoc Thanh,

No bug. (4B, 4A) have no room.

I have encountered a similar issue with the teacher "Leonardo da Vinci."
I have already double-checked the rooms and buildings.
I wish for all teachers to remain in the same building throughout the day.

You didn't add room constraints at all. You must add room constraints.

[Volker Dirr]

I guess in your data set you want to (should) add room constraints for students. Set students home rooms. For example give students set "Truma A1" the room "Sala A1".

Thank you a lot.
Totally worked now!
