Billy, if it let you process them then it’s probably fine so I would just leave it as you had originally planned.
The rules for number of characters in titles, bullets, etc do vary for each category (based on the Category Style Guide) and it appears each category police the rules in different ways.
You’ll find out for sure once you make the listing go live. If the listing is not approved then it will get suppressed. Which is not a big drama as you just edit the listing to get it approved.
As I said, everything is probably fine so don’t worry about it much. As a precaution, I suggest that you have another version of your bullets (with less than 100 characters per bullet) ready to go just in case you need them at a later date.
