Overleaf & LuaLaTeX: Font Warning: Some font shapes were not available, defaults substituted.
I'm making an overleaf project template for our research group. As I'm not very experienced in using cls files in Overleaf, I uploaded all the files to an Overleaf project. After solving minor problems I managed to compile using LuaLaTeX. The output pdf for a proposal has everything I need except the fonts. I received this error in the log file:
Font Warning: Some font shapes were not available, defaults substituted.
Is there a fix for this font issue? The editable Overleaf link is below. Also, logfile and output pdf are attached.
