How to reduce the size of the Target Object Indicator

I recently installed TheSkyX SAE version 10.3.0 (Build 8842) on a new PC running Windows 10. Everything seems to work OK, but one issue I have is that the Target Object indicator is huge compared to the relative size of everything else (see attached image). It is so large it is hard to see what it is pointing at. Is there a way to reduce the size of this indicator?
