If you have a pageview event that is very broad (or if you have Heap installed on a single page application) then the array of different navigation options will result in seeing many repeat pageviews.
There are a couple of ways you can workaround this:
Exclude that page from analysis by clicking the Exclude button on the pageview as it appears in your analysis.
Go to the users page, filter for users who have done sequence: that pageview –> that pageview –> that pageview, and see if you can understand why your users tend to do this pageview multiple times sequentially.
For example, you might notice the path remains the same, but the hash value changes, thus triggering another pageview. To prevent this, you can create a defined property to return the hash value, if it exists, instead of the path. Grouping by that in the Paths chart can offer more insight and clean up the chart.
Alternatively, you might notice that the pattern is generated by obvious bots, and can exclude those IP addresses.
