Attending a bat mitzvah and the mitzvah card we got has G-d written out. Is that okay?

Hello! As noted above. I hope it’s okay to ask this. My family is not Jewish but we are attending a bat mitzvah. One of the cards we got has G-d written out and we just noticed. It’s a specific card for a mitzvah but I thought Jewish people don’t usually write it out…is it okay? Should we make the o a dash with a sharpie instead? They are not orthodox Jewish but we are still unsure and don’t want to be rude. The synagogue it’s being held out has G-d on the website. Should we cross it out/is that really disrespectful? Thank you!
