Wrote: I'm using those exact same helper parts without any problems in my instructions (using LDCad and LPub3D). I downloaded the arrows from holly-wood.it and then placed them in my unofficial files folder. From there everything worked fine.
The problem might be that you put them in unofficial/helper. I believe (but don't qoute me on that) LDCad and LDView don't look into subfolders. So either add unofficial/helper as a (2nd) unofficial library in LDCad/LDView (if you use LDView as renderer in LPub3D) or just put the parts in the root unofficial parts folder.
I followed your advice and now I can see the arrow in both LDCad and LDView. Oddly though, even though I have LDView selected as render engine in LPub, I don't get the arrow there.
