Auto Actions - On Profile Edit, Copy CB FIeld to a Different CB Field

I'm pretty sure it takes 2 saves for the full update. Here is what I have:

Action: Field
Triggers: onAfterUserUpdate
User: Automatic
Access: Registered
Conditional: None
Field: First Name
Operator: Set (Field=Value)
Value: [cb_custom1] - [cb_custom2]

In the CB Config I have:
Name Style: First and Last Name Field
Name format: Name Only

On the first save I can see the changes for the Last Name field reflected, but not the changes for the First Name field (which is a combination of the 2 custom CB fields). On the second save, the changes from the first save are reflected. I can see this in the User Profile Page Title tab which uses [cb:userdata field="formatname" /], and I can see it in other components that use the formatname.

Ensure you're using latest CB Auto Actions (5.1.3). Next ensure you're changing both the fields in a single field action (you should see a + button to far right of field parameters). This should allow the two to update at the same time. There's no reason for it to need a double save unless a second save is overriding the changes (possibility if you're using 2 field actions in a row).

I'm using 5.1.3 Auto Actions.

I'm combining both custom fields in the same Auto Action and the same Field Action within. No need to add another Auto Action or another Field Action.

The actual name fields update on the profile, however, the Formatname does not until a second profile update/save is done. The fields in the database update, but the Formatname does not reflect this throughout the site. Ive hard refreshed, but still nothing (a second save is needed). I can show you privately if you like, or privately send you a video/screenshots.

Format Name doesn't have any storage. It pulls its values from Name, First Name, Middle Name, and Last Name. If you're only updating Name then CBs First, Middle, and Last Name fields have not been updated yet, which is why it's taking multiple stores. If you're using First and Last format then you need to update Name, First Name, and Last Name.

I'm currently updating middle name. I sent you a screen capture.

You need to also update Name, but you'll probably need an Query action for that if it's not showing up in the field dropdown. Name is stored in the _users database table and is what most 3rd party extensions are going to use (they don't know CBs First/Middle/Last exists). The Format Name field also only uses Name (it automatically splits it using our getNameFormat function) so Name has to be updated too. To do that you could use the below query action (after your field action).
