If you had already turned it off using SBSetting then it will NOT be removed because the OS is completely unaware of any adjustments you have made in SBSettings.
To remove it completely, turn it ON in SBSettings, install the tweak again in Cydia, then check SBSettings again. You may have one or two entries for the same tweak. Regardless, make sure they are both turned ON, then remove the tweak using Cydia. That should remove it fully.
Turning OFF mobile substrate tweaks using SBSettings should only be used as a temporary measure, and you should always remember to turn them back ON before trying to remove the tweak.
