[Gmsh] Mesh coarsening between two refined lines

Dear Sir or Madam,
I run into a problem currently with GMSH.

I have a rectangle LxH that I want to mesh.
Within that rectangle I have two lines that split the whole rectangle into 3 subdomains. Along those lines (a<=x<=L) I want to introduce a fine mesh.
Thereto, I use a Field (Line attractor and Threshold). This is a matter of choice, since the problem will be upscaled towards more and overlapping refined regions.

However, now I realise that between those two lines no mesh coarsening takes place, although it actually should.

Is there something that I am missing or is there a more neat way to do it?

Attached is the geo-file. To mesh that model I use the default 2D meshing option.

Best regards,
