It's best not to start by modifying Arial. You should start from scratch,
and then this problem doesn't arise.

For some reason, FontForge isn't displaying all the alternative language
name strings that are set to "Arial" in the font, but TTX/FontTools will
show you what they are.

To fix it, I'd suggest you save your font to SFD, load that SFD into
FontForge and regenerate it.

You can see how Fontconfig understands your font with the tool fc-query. Type

fc-query nameoffontfile.ttf

and look at the lines starting "family:" and "fullname:". For the font you
attached, you'll see Arial in there. When that's gone, it's fixed.
