Dear Rishikesh,
the last version of the files are ok, except rca_pnml. Input a0 is an output pin. Unfortunately, you triggered a bug. We have solved it and the new version of MagCAD will be released soon. Modify the rca layout using an input pin for a0 and everything will be fine.
Update to version 2.9.0 as soon as it will be available and fell free to report any problem.
