How to show weeks and month in course duration

[Chamruntraining]

Hi ther I would like to show 14 weeks for a course as course duration(below screenshot): http://prntscr.com/tcjnmv But on front-end it converts to days like this: http://prntscr.com/tcjo3o but I just need to show "14 weeks", not convert it to days. How can I fix it?
