Sequencer- Cannot change multiple selected spawnable's class

Only the first selected spawnable actor binding will have its class changed when selecting 'Change Class' from the right click menu.

1. Create a new Sequence
2. Add multiple spawnable static mesh actors (such as Cubes)
3. Select all of the actor bindings
4. Right-click and choose 'Change Class' and select a different actor class
5. Note that only the first selected actor changes its class

Expected: All actors would change class.
