Picklist values out-of-date in Campaigns

Picklist values out-of-date in Campaigns

Hi

I use a CRM (Global) picklist set of values for my field "Connection Strength" (see screenshot 1).
.

I use Campaigns to follow-up and change the Connection Strength value depending on their stage.

The picklist values that appear in the dropdown for this field in Campaigns is out-of-date and doesn't show the values I need (see screenshot 2).

How often does this update?  Is there a way to force it to update?

Many thanks,
David
