Intermittent datepicker issues with filters

[x9sim9]

When using the datepicker with activeadmin filter, the datepicker when clicking on the input field seems to be very buggy, sometimes showing the datepicker other times not triggering at all.

If you click on a filter field, somewhere else on the page and click back on the field a few times it replicates the issue. Sometimes the page loads and it is not shown at all.

No java-script console error messages are being shown.
