hi @zizjasper thanks for using my theme!
this easy to fix. just go to Appearance > Customize > Sidebar Settings and choose Left sidebar or No Sidebar then Save. Once the settings are saved, you can choose Right Sidebar and save again. Now Sidebar widgets will be shown as expected.
Version 2.0.2 is already approved and will be available soon at ww.wp.xz.cn and its has a fix for this bug.
If you like RedWaves lite please rate it 🙂 i really appreciate it!
Regards!
