This seems to be number 11 from the known CalculiX limitations list. Check the referenced ccx forum thread and maybe post there: Zero reaction moment when reading from ROT NODE in 2D - CalculiX (official versions are on www.calculix.de, the official GitHub repository is at https://github.com/Dhondtguido/CalculiX).
Of course, reaction forces/moments will appear only in nodes and DOFs with boundary conditions (zero or non-zero) applied. However, RF in CalculiX also includes the applied point loads.
Try with equivalent 3D solid model instead.
