Thanks for the reply, Tkael.
My home system is Diaguandri. Tested also with Sirius, Sol and Asellus Primus with the same result. The Home system box remains purple as though it doesn't recognise the name, and no station names are visible in the drop-down menu below.
EDDI v3.3.2 following a clean reinstall and reimport of EDSM logs.
Reproduced for Diaguandri but not Sol with my current EDDI.sqlite, and for all systems after removing my EDDI.sqlite.
