Custom Fields not appearing in Event Creation until after Save

Heya,

Hope all is well with you and yours...

Have had a report from the guy in charge of creating our cycling club events, that the custom field I added for use in some of the categories is no longer appearing in the Event Creation form until the event has been saved.

Obviously he can hit 'Save' halfway through editing to force it to appear - but he's convinced that until the last couple of months, the Custom Field was available for entry as soon he created a new Event - without having to Save.

Is this something you can explain?

Thanks in advance,

-Craig
