NET rigctl reports wrong Antenna set/get caps

[PianetaRadio]

I have Yaesu FT-991, it has only one antenna selection and the newcat correctly reports no antenna selection capabilities.
But if I connect it via rigctld this cap is wrongly reported, for example this is the ouput of rigctl connected to rigctld connected to Yaesu FT-991

`rigctl -m 2
Rig command: /dump_caps

Rig command: \dump_caps
