[Help] Stamp & Align, not working on same type of object?

So I'm trying to Stamp & Align multiple dock segments, but for some reason it won't align them properly when they're the same type. For instance aligning "dock_ramp" with "dock_straight_30m" works perfectly fine, but when I'm trying to align "dock_straight_30m" with another "dock_straight_30m" the other one will just get moved on top of it (copies exact coordinates). So I'm wondering if there's a fix for this?

Here's a video showing what I mean:

As you can see the second one isn't snapping as desired.
