My guess is you've some sort of CSS conflict from your Joomla template or custom CSS was added that could be doing it. It's working fine on our demo site below.
Ensure everything is up to date and switch to default Joomla protostar template to see if it could be a template conflict.

JCH Optimizer should work fine with CB. We use it here, but you need to ensure CSS order is maintained or you could get issues with CSS overriding each other. It's also worth noting you have to clear JCH Optimizer cache separate from Joomlas. See below for what JCH Optimizer settings we use.
