I'm seeing an issue with one of the Deployment Monitor reports, under Home> All Indexers. At the bottom of this page is a chart showing status of the indexers, in my case there are 2. If I click on the second indexer it takes me to a Indexer Properties page with a default time of 30min. If I change this time picker to another value, such as 24hrs, the page refreshes with the wrong indexer.
what version of DM (and core product) are you using? We'll take a look...
