This should read
\begin_inset Formula $R=Rh/2+(ZZ-4)$
\end_inset
\layout Standard
but with this one it gives errors
\layout Standard
\begin_inset Formula $R=Rh/2+(ZZ-4)+K_{ab}$
Note the extra '$...$'.
Without these, you end up in math text mode (indicated e.g. by the
upright black text instead of 'math blue italics'). An underscore within
math text usually creates trouble.
You can convert your formulas with 'M-x math-mutate simple' (or M-m t i)
or if you have lots of them by search&replace in the .lyx file.
