The most straightforward way to verify this is to check the Webpages
table. There you will see immediately if the value is multiplied, like in this example:
To find this table, you need to click on your preferred conversion. On the top left, you will find the Webpages
table.
If you get this error, there isn't anything wrong with your setup. It is just a timing issue.
If you created a conversion a day ago, with a click-through window of 21 days, you might still get some gclid's
that are 2 days old or more. This means that the specific gclid
in question can't be used for this conversion, because it is older than the action. This issue will solve itself after some time has passed and it will not affect your results.
Littledata sends all orders, not just those originating from a campaign. This notification is expected and can be safely ignored.
This is a false positive. The dashboard expects the client-side tag to send user-provided data, but the data is already being fed server-side.
