Changing "name" of custom field causes problem

I have a custom field which is type of “Select List” and I am using colours for events.
If I change the name of this custom field, all events get the colour of the first entry in the list.

name - is name of db field, if it changed - calendar will lost all saved info for that field.
If you need to change just text in the lightbox - change the Description of the field.

thank you! (and sorry for spamming the whole forum with my requests!)

the scheduler works ok if change the name of table “event” to other name also the database fields?

The name of table is hard coded in the plugin, so it is not possible to change it. ( you can use standalone scheduler if you have some specific table as event’s info storage )
