This works fine for me, which makes me believe something is astray with either your procedure or your installation.

- I have the ik/fk switch
Further suggestions on what may be wrong:
* You're using MakeHuman 1.0.2. All development is targeted at 1.1.0, and it's possible newer mhx2 versions are glitching with 1.0.2.
* You have made an export for mhx2 a while ago with a different version of mhx2, and try to import it with a newer mhx2 which has changed somehow
* You have exported a character from MH with a skeleton which was not "default" or "default-no-toes"
What exact versions of MH and MHX2 are you using? And what options and skeleton are you using when exporting from MH? I see from the screenshots that you're using blender 2.76, which should work fine.
