Short description of error
Data transfer modifier vertex group selector is ignored with freestyle edge marks and freestyle face marks.

Exact steps for others to reproduce the error

Default scene, select cube
Subdivide level 2 the cube, and apply the subdivision modifier
Duplicate the sphere and place it nearby
Select the original sphere, and in edit mode select some edges, (like the blend file)
Make those selected edges "freestyle edge marks"
Go to object mode, and select the duplicated sphere
Go to edit mode, select a contiguous area of faces, 4 in the blend file
Create a vertex group and assign the selection to this new vertex group
Leave edit mode, and add a data transfer modifier
In the tab for data transfer modifier, select edge data, then tick freestyle marks, use topology for geometry mapping, for the source object use the original sphere, for the vertex group select the vertex group previously created.
Press the Generate Data Layers button
go to render options and tick the freestyle feature
go to render layers, in freestyle line set, tick the option "Edge Mark"
Render
The two spheres have the same set of lines drawn, ignoring the vertex group.

The expected result would be to have the original sphere with the full freestyle set, and the duplicated one with the freestyle set given by the vertex group.
I Tested Data transfer modifier vertex group selector with:

Vertex data: Vertex groups.
Edge Data: Sharp, UV seam, Subsurface crease, Bevel Weight, Freestyle mark
Face data: Smooth, freestyle face mark
And all of them work as expected, except the freestyle ones. the blend file, DataTransferModifierSelector_FreestyleBug.blend have these tests.
