Hi Team,When I switch you Layout mode and try clicking on the different option in emulator it throws below attached error. I am able to arrange the width of the component in the grid. I am using SPA AEM 6.4.3 version. But WKND sample works as expected.

How did you created the SPA project for 6.4?I am using AEMaaCS and SPA layout mode works fine there for custom projects.
