Hatching in Librecad

I made a circle in draftsight and done hatching with pattern fill.
But when i open the same file in Librecad, it shows only circle wihout hatching.

When i re-engineered the hatch entity section of files made in both CAD software i.e Draftsight and Librecad.
The diffference is only one group code
92      boundary path type flag
          0 = Default; 1 = External; 2 = Polyline;
          4 = Derived; 8 = Textbox; 16 = Outermost


In draftsight, it's value is 7 that is not defined in DXF specifications.
 
And in Librecad, it's value is  1.

Why it is???

Those values look like bit values (each digit may be 0 or one, indicating the presence(1) or absence(0) of a feature).
 0 = Default; - 00000000b
 1 = External; - 00000001b
 2 = Polyline; - 00000010b
 4 = Derived; - 00000100b
 8 = Textbox; - 00001000b
16 = Outermost  - 00010000b

7 means 00000111b so a combination of External, Polyline and Derived
Not sure how familiar are you with programming, that's why I spell it out.

Then why Librecad not supported this value 7 of 92.
It is showing hatching on this value.

Please add a bug report if you did not do so already. I can't look into this right now.
Thanks!
