Yeah, the reason is with new filter in view - "Statistic attribute name". It is list of existed attributes of safes, unsafes and unknowns (if at least one checkbox of "Statistics/Safe", "Statistics/Unsafe", "Statistics/Unknown" with existing data is checked). If this list is empty, javascript failes collecting the selected attribute. This list is not updated automatically until the job status is changed (when the entire page is updated).

The first solution is to hide this filter. If you update the view when it is hidden, this filter will be deleted (if it was set before). To show the filter you have to update the page, or wait until the job status is changed, or find job with unsafes/safes/unknowns. If your view doesn't have "Statistics/Safe", "Statistics/Unsafe", "Statistics/Unknown", you have to enable it, save the view, update the page and then you can see list of attributes. Obviously it's bad solution.

So I'll just replace the list of attributes' names with text field. When the field is not filled, the statistic will not be shown even if checkboxes "Statistics/Safe", "Statistics/Unsafe", "Statistics/Unknown" are checked.
