Could you please give some examples of matrices that give you the errors?

This can happen when you are in Approximate mode. When doing symbolic operations, it is usually better to use Symbolic and Exact modes. In MODE -> CAS, UNcheck "Numeric" and "Approx".
Do this Before you enter the matrix or data. If you are entering data with decimals, enter it as fractions (you can use ->Q or ->Qpi in the Convert -> Rewrite menu (Leftshift 6 "Convert", "Rewrite", NXT)).

Please check that the 1-row matrix is a matrix and not a vector:
If you are entering a 1-row matrix manually, use double [[ ]]
if using the matrix writer, uncheck VEC:
