Lightmap variation on duplicated objects

Hello !

I’m pretty new to Unreal Engine and I encountered some problems.
Actually I managed solving most of my problems by trying new methods, tricks and researches on the web, but I admit that I don’t understand the next problem :

I have got a big platform on a boat, composed by 4 copies of that object and rotated by 90°.
As you can see on the image below, the lightmap is not continuous and there is a real big “seam” of light between each part of that platform.

Did I miss something to do? How can I solve this issue?

In advance, many thanks!
