Ohif Viewer v3 Stable version - Missing Toolbar at Basic Viewer

After git clone the ohif viewer and switch branch to v3-stable, finished built and everything go fine, but when go inside the single study for basic viewer, the top toolbar is “missing”. I check the demo site at https://v3-demo.ohif.org/, also same situation. It is different with the video in the Build for Production | OHIF.

Please help me on this?

Thank You
