Hello! I noticed that you introduced this easy-to-make grammar error while making a grammar cleanup.
This is a tricky part of English, and even professional writers get it wrong on occasion. In this case, "it's" is a contraction instead of a possessive - "it's" means "it is", and "its" means "belonging to it".
It might help to think of other pronouns and follow the same rules that they use: "he's", "she's", and "it's"; or "his", "hers", and "its".
No worries; as I said, it's an easy and common mistake, and it's easy to fix.
