Help Lost color code options on Google Calendar

[dochenry]

I use the same Google Calendar on 2 identical phones (Motorola Turbo II) on Verizon. Suddenly today, my second phone no longer allows me to set up appointment with a choice of color code. The most noticeable difference I see on the new or edit appointment page is the absence of color code choice and another button with a Lock icon captioned "Calendar default." Appointments already on the calendar still allow editing of color code. I want to return the Calendar on that second phone to the original settings.
