Strange behaviour

Has anyone seen this sort of behaviour before?
Nik Collection clean installed onto Mac Pro Mid2012 Quad Core OS10.13 (although this behaviour also happened in OS10.8) Photoshop CS6.
In both types of Nik Sharpener and Dfine although it appears to run there are no numbers or titles (see attached images) Viveza doesn’t appear to launch at all but shows as having launched in Photoshop without effect (incidentaly this behaviour is identical in Affinity Photo 1.8.3). ColoEfex, Analogue Efex HDR Efex and Silver Efex all work OK.
I’m at a loss to solve this and therefore wary of upgrading to the latest version.
