Bug: "File Mask" don't work as expected

Example: The pictures in an site are all recognised as JPG but they are all coded as WEBP So I will use the "File Mask" feature with the expression "[name].webp" But in the resulting ZIP all files named [name]-webp (with an "-" instead of ".") Tried some other special signs, all resultet in "-"
