Pivot table has the maximum data points

Pivot table has the maximum data points

When I make the pivot table that I need, he says:
Data points exceed the maximum rows limit allowed in Pivot tables. 'Show Missing Values' option applied partially to show the pivot.

But I only have 5 columns and maybe 80 rows. How is this possible?
(I synchronyzed once more data but I have set that back to less data but I have still this problem)

Thank you :)
