Please try with the current development release (5.0-6362 as of this posting): https://dolphin-emu.org/download/
You may also want to check if it's related to some custom configuration. Try using the Refresh button in the controller config, resetting your settings, and trying again. You may also want to try adding a blank portable.txt file to the Dolphin folder, which will force Dolphin to not use the centralized settings in your Documents folder; which should typically reset settings in the emulator to default.
There is ongoing work to revise the handling of the emulated motion controls (i.e. shake, etc.), but I don't believe SMG2 is currently related to any known control issue.
