As I am talking to my co DM and he said
"I made a mistake with casting one spell per round rules. You can cast a spell as a bonus action and another as an action, or reaction, as long as only 1 spell slot is used.
So, you can, for example cast a cantrip which does not use a slot and another spell that does in the same round as long as both are not the same type of action.
