Newly added Emojis disappear from Calendar events on iPhone 15 Pro Max after update (previous ones there)

Help with emojis and calendar with new update! I updated my iPhone 15 pro max last night. Since the update, I no longer can add emojis to my calendar events. I need them to organize the different events for work/family members. What can I do to get my phone to allow keeping emojis onto my events. Currently, if I type them in, they disappear once the event is set to the calendar. My previous emojis before the update were there. HELP!!!!
