I've noticed the results from Filters can sometimes vary for no apparent reason within a minute or 2 of refresing the filter. Nothing has changed in the data to cause the differing results. For example, I ran a filter to return issues using certain criteria and one minute I got 88 records and a few minutes later I got 84. Nothing had changed in the data. I have noticed this a couple of times. What would cause this? I am pressing F5 and the search button to make sure I am getting the latest data.
