So, the following was tested again:
TACAN Tune: " TACAN Tune X-Ray zero eight five" etc. Works without problems.
Link Tune: "Link Tune two five decimal zero" etc. Works without problems.
Radio Tune: "Radio Tune three one zero decimal five", ".. decimal one two five" etc. Works without problems.
The problem is not with plugin functioning.
As recommended earlier, do a hard reset by removing Database and Config subfolfders to exclude any snags.
Get a fresh profile via Config/Export, Import in VA, restart and follow the FINISH steps.
Invest time in improving your recognition rates following the manual syntax, practice speech pacing, use voice training.
Also suggest to check out VSPX: some people get best results with that.
