Thanks, Tammy!
I did refer this document earlier. I wasn't sure about a couple of things, though:
1. Does this document also apply to version 1.30 and later?
2. Does this specifically mention anything what calculations are not supported? I may not have understood it that well. I could see that it talks about Local calculations not supported. However, based on my experience, I could infer that only % type calculations do not work. Calculations involving "+" or "-" either show up correctly or can be created in Lumira itself.
Anyways, thanks for your time to respond.
