Error saving view with multiple keys of the same name after updating to 8.3.1

After updating a Drupal installation from 8.2.x to 8.3.x, I cannot save some views. I might be wrong but I think this might have sth. to do with the fact, that these views contain two filters on the same field/property - one of them appended with "_2".

The error message is:

InvalidArgumentException: The configuration property display.default.display_options.filters.type_2.value.page doesn't exist. in Drupal\Core\Config\Schema\ArrayElement->get() (line 74 of core/lib/Drupal/Core/Config/Schema/ArrayElement.php).
