Inkscape missing fonts

[dweavers]

Inkscape is not my go to software but comes in handy (nomally use adobe illustator)
I have been given a file from a cutomer who kept fonts as fonts and of course I dont have some of them (normally not too much of a problem)
But this is new to me as they are listed as Arial Black, Arial Black_MSFontService for example, photo has been added
Question is what is _MSFontService? and how do I overcome this querk?

Best guess is that it's the system (Windows) version of the font your customer used. If the file names don't match, a lot of programs will see fonts as "missing".
