Problem: Only 5 markers are displayed on a map that should show many more markers. If I check the Maps address cache in Toolset > Settings > Maps, there are no addresses cached.

Solution: The minimum required MySQL version is 5.6. In this case, the server did not meet the minimum requirements. Updating the MySQL version is the best solution in this case.
