[NTG-context] Custom type-imp file creating empty lines

Dear list, I've played a bit with a custom type-imp file (partly inspired from the wiki https://wiki.contextgarden.net/Alegreya_Typescript). However, the file I ended up with seems to create some empty lines at the beginning of the document (if I use the default or another font this vanishes, so it really comes from that file). Could anyone enlighten me? The file is attached. BR, Alex
