Can't see all installed color management profiles

[grobot]

Hi ,

I'm just started creating a photography zine using Scribus 1.5.5 on WIN10 machine. I want to print it on my Epson SureColor P600 printer using specific color profiles from different paper manufacturers such as Hahnemühle, Ilford...

I've downloaded the icc profiles and installed them. I can choose all of them in Photoshop and I can see them under /windows/system32/drivers/color but I cannot choose them in the Color Managment settings in Scribus.

I don't understand what I'm doing wrong?
Thanks for any help  !
