Corrections - Genitive

Hi! Today I’ve written and sent for a check a text where I used forms like Lisas Freund to indicate possession. However, when I got corrections I was surprised to see it corrected and replaced with Lisa's Freund.
What form is the correct one?
I used to believe the first one was correct and it’s correct according to the rule, but still would like to clarify this moment.

Obviously, that was our mistake. It’s definitely correct the way you wrote it:
Lisas Freund
We sincerely apologize for this mistake. :pensive:


Thank you for the reply!
