Apple snail shell help.

[Elephant nose 4]

Hi my poor apple snail seems to have cracked her shell, I think she landed on my pleco cave,the crack seems to be growing? I've moved her from my elephant nose tank to my boraras. My other snails are doing great no shell problems. I'm wondering if I could patch her up or should I leave it? I'm feeding lots off calcium foods and added calcium. Shes moving around ok so isn't showing any signs of stress.
Heres a pic off her.
Thank you

I have heard of patching but I’d Google it. I have one with a hole and he does fine.
