IIRC 'Invasions' aren't counted as 'Invasion Job'. The contract itself is also kinda buggy for people with counting the Invasion-enabled mode/contested territory. 'Invasions Jobs' as far as I can remember are the icons with the yellow outline/yellow icon under it - currently its Adamant, Europa: Bounty Hunt - its got Invasions Enabled on the modifiers. Its the same yellow icon as you'll see below the Contested Territory jobs.
