There are 2 component sets:

IW Bootstrap 3 (all controls and units have the IWBS prefix), and IW Bootstrap 4 (all controls and units have the IWBS4 prefix). They shouldn't be mixed together.
They are basically the same controls (with small differences) but one is based on Bootstrap 3 and the other is based on Bootstrap 4.

So, if you are using IWBS buttons, please use only IWBS3 components and units in your project.
