This is not uncommon when the monitors have not finished running.

Here are a number of guides that will give a ton of information about this:

If you tell us which monitors have not run then I am sure we can get you a driving sequence that will help you force the monitor to run. It will happen in just normal course of driving but this may take weeks to months.

Please let us know if you have other questions. Thanks
