How to put a blank space in the translation of Teacher Widget

Hi! WPLMS is wonderful! Congratulations! I'm using WPLMS in Brazilian Portuguese. In the page of any course, there is a widget about the teacher. In English, there is a item called "More courses by #Instructor#". In Portuguese, it appears as "Mais cursos do#Instrutor#". As you can see, it is missing an blank space before the name of instructor. I've searched in the .po file and there is nothing about this. I searched in all the widgets, and not found anywhere to change this. So, where should I go to add that space in the translation? Thanks!
