We saw something similar when working on the columnsets, but as far as I
remember it was resolved. Apparently it is not. What is (or at least was)
working was to use \numberhere instead of \startplaceformula
\stopplaceformula, so you can try

\startformula
c^2 = a^2 + b^2 \numberhere[eq:foo]
\stopformula
