You expect to have indication of a NDB into the VOR instruments and fail? No wonder. 8-)
VORs and NDBs are fundamentally different and are read on different instruments. You can't read the NDB on the VOR instrumentation, and the way around is true also.
On the picture below you have a indication of where to expect, on the default Cessna 172, to read which.

The two instruments display only that information, and do not cross reference. The VOR instrument doubles as ILS GLIDE and LOC indicator and nothing else. The autopilot too is unable to lock on a NDB, but only can follow a VOR radial.
This is the way things are.

There's but one real cure for human stupidity. It's called DEATH.
At the moment mourning the assassination of sarcasm and irony for the good of the "higher".
