UMLEnumeration convertion failed

[leo4048111]

I tested the example code for UMLEnumeration convertion and the conversion result turned out to be empty.
Code(Copied from readme):

/* Test header @ toori67
 * This is Test
 * also test
 * also test again
 */
#ifndef (_WEEKDAYS_H)
#define _WEEKDAYS_H

enum Weekdays { Monday,Tuesday,Saturday };

#endif //_WEEKDAYS_H

conversion result:

Any solution?
