My FKS did this on 1 pair of skis when I first got them. Solution was to crank the forward pressure up another few notches. They still come off completely fine and the tab is a little bit behind the notches. Massive disclaimer, if you do this and your leg snaps and you die, not my fault. But if you're riding FKS180's you should be OK with this.
Google FKS forward pressure, theres tons of stuff on the net about it, mostly comes down to the phase of the moon and the direction the wind is blowing when they are adjusted (or more likely it's to do with different thicknesses/wear on the heel/toe lugs).
You'll know if you've gone too tight because when you clip the boot in the toe will pivot forward slightly. It takes a bit of time with a screwdriver but you should be able to sort it.
For what it's worth, I skied for a couple of days with that little bit of play in mine, no issues, they never fell off or anything. Just wait until you have a big gnarly almost-crash and you'll see how far they will travel before they let you go.
