go to monitoring->events, set some filter period (to make a better point, choose some period for which there is no data).
open dashboard. clicking on 'last change' column values in 'latest issues' block opens event view, but it keeps the previously set filter.
this can easily result in output missing information as filter was not set with that trigger in mind.
opening event list from another location should reset the filter (the same problem happens when navigating from triggers view, maybe also other places)
