I've discoveres a bug in KLWP that seems to cause quite an inconvenience. The new unlocking presets feature is amazing useful, but appears to not be fully working. Ideally, a preset would be fully unlocked when authenticated with a Google account. However, currently, a preset that has been exported as read-only can be loaded and exported again, but copying of objects inside of the preset is still locked and disallowed.
I am hoping this issue can be fixed in a future update of KLWP.
