Did you do a manual scan or did one of the scanning targets scan the asset?
Please note that scanning targets respect the scanned item interval. A scan item interval determines how often an item is scanned. Software, for example, is scanned once per 24h (1 day). More information about the scanned item interval can be found here: https://www.lansweeper.com/kb/115/managing-how-often-specific-data-is-scanned.html
If you want to be sure that the asset is fully rescanned, you can navigate to the asset's page and use the Rescan Asset button in the left-hand pane. This option will fully rescan the asset.
