Hello @edwinv,
Welcome to the Community.
Klaviyo attributes the value to an email campaign when it is clicked/opened. By default, conversions for each campaign are tracked up to five days after an email is sent; you can adjust this conversion period for your account by navigating to the Account > Settings > Email page and scrolling to the Email Conversions & Smart Sending section. Klaviyo Conversions are attributed to emails based on a Last Touch Attribution model, as explained here: Understanding Conversion Tracking. To add the Revenue metric to a profile you would need to add the Placed Order metric with the 'Value' definition.
A conversion occurs when a recipient opens or clicks your email message and then takes another action (such as placing an order) within the conversion period. By default, the conversion period is 5 days, but this setting can be adjusted in your account's email settings.
We associate opens/clicks/revenue with the email. Here is an example of the process; if someone was sent a campaign email on Aug. 1, opened and clicked on it on Aug. 2, then made a purchase on Aug. 3, we'd associate the open, click, and purchase with that message. This is a great guide on all our campaign analytics.
It would also depend on your settings for your metrics as it could be looking for data within a different range. Example:

With this current account settings, this means that any customer who opens or clicks an email 1-5 days before placing an order will count towards the Klaviyo revenue attribution. If a customer opens or clicks on two different emails in the 1-5 days before placing an order, then the order will be attributed to the most recently opened or clicked email message.
Additionally, I would recommend taking a look at these super helpful articles for more information about Reporting:
I hope this helped,
