If a character has a bonus action and an action to take, then the character will perform both, even if they are both spells of 1st level or higher. This is incorrect behavior, because 5e D&D balances bonus action spells by preventing you from casting other spells that same turn (except for cantrips with a casting time of 1 action).
Steps to reproduce the behavior:
Go to Battle Sim.
Create a party with a cleric.
Add a CR 3 archer (if the monster is too weak, the cleric won't bother using both spells).
Hover over the cleric and see that they've cast both Spiritual Weapon and Bless.
Expected Behavior:
The cleric should have either cast Bless or cast a Spiritual Weapon + Sacred Flame combo, whichever the algorithm believes is more optimal.
