not sure what the reason is - it kinda depends on different things.
you could try running this query to see:
SELECT TOP (1000) [SoftwareID]
,[AssetID]
,tblsoftware.[softID]
,tblSoftwareUni.softwareName
,tblSoftwareUni.SoftwarePublisher
,[softwareVersion]
,[Installdate]
,[Lastchanged]
,[CurrentUser]
,[MSI]
FROM [lansweeperdb].[dbo].[tblSoftware]
left join tblSoftwareUni on tblsoftware.softid = tblSoftwareUni.softid
where softwareVersion = '98.0.4758.81'
