BE AI runs. All time is the default, so every loaded investigation is listed, however old it is.
Open BE AI runs. The period menu says all time. Example Co has one investigation: the disk alert on Accounts server, finished, classified known_growth. It ran on 21 September. Last 24 hours, last 7 days and last 30 days are the other choices. They look at when the run started.
Set the menu to last 24 h. The disk investigation drops out, because 21 September is older than a day. The count says 0 of 1 runs match, and the table says no runs match these filters. The investigation is still stored. Last 7 days and last 30 days keep a run whose start is inside that window. Set the menu back to all time and this one returns. Clear filters clears the other menus as well.
