I have the exact same issue, it’s the multi-select ‘checkbox’ fields that display (0 selected) instead of the descriptive placeholder text, that tells users what they should be selecting.
I’m also using the Kleo theme however the Kleo support says it has nothing to do with the responsiveness of their theme. Which I’m inclined to believe, since changing the theme results in the same problem, like Mickey mentioned. So it must be happening somewhere in the Buddypress or BP-search form code. Can we get any help with this? There was one other topic posted 10 months ago, with the same issue and no information was received there either?
