Categories/Industries not showing up while doing Preview

[GR]

During Offer creation, I have selected the categories "Big Data:, "IoT" and "Security". However, during preview of the offer (prior to going live), I only see "Analytics" and "Security" as showing up.

I had also chosen "Manufacturing" and "Real Estate" as the Industries. However, neither of them appears on the left side in the preview!

For other offers, the chosen industries show up, but the categories chosen are not all listed!!

Thoughts on how how to fix?
