Why my text does not work on my upper wing, it works on the side and lower wing

I am using Rhino 5 for mac.
I used photoshop to do the texture, i do not know why the text does not show on the upper wing, however it shows on the side and lower wing.
It will only appear if i Click the blue ball for rendering. Who knows why?
I do not have decal on Rhino 5 for mac as well, any suggestions?
Thank you very much.

Problem solved, after I closed the software and reopened again! It appears! Thank you.
