Dynamic URLs that you have not configured to be interpreted by a URL replacer cause:
To solve these problems, stop auto-learning for those URLs (right-click them in the auto-learning report and select Stop Learning), then configure a URL replacer. For details, see How to adapt auto-learning to dynamic URLs & unusual parameters.
If you decide later that the URLs were not, in fact, dynamic, you can resume auto-learning: right-click the URL in the auto-learning report, then select Start Learning. Otherwise, for dynamic URLs, you can delete split auto-learning data (see Removing old auto-learning data).
