I can’t reproduce, I get bold text here: test.pdf

I have texlive 2017

log file:
test2.log

pdf file:

The log is not telling me much. If it works with XeTeX but not LuaTeX then most likely it is a bug in luaotfload, but I can’t reproduce this to do any debugging.

One difference is that I have the fonts installed in system font directories, and your example is reading them from TEXMF tree, so that might be related. Can you try installing the fonts and see if it makes any difference.

[khaledhosny]

I removed the system fonts and even luaotfload cache and no difference.

[seloumi]

I have installed the fonts and the result is the same: bold italic rather then bold !

This really looks like a luaotfload bug, the fonts’ metadata are correct as far as I know, and no other application has issue with it.
