Tiger-M only 3 passive modules?

In the ship tree i noticed that the tiger-m only has 3 passive modules while every other T4-2 ship has 4.

Is it just a tooltip bug, or should i avoid that ship and buy the tiger II (which should be tiger mk II, following the vanguard name scheme)?

some ships are lacking a passive slot but can carry more missiles than their respective counterparts

that sucks :frowning:

ty for the reply
