It actually seems like the GUI only displays one of the inherited 
annotations on the Experiments page. This should of course be corrected 
to display all annotations. Note that this is just a display problem. 
All the inherited annotations are stored in the database and can be 
viewed from the Raw Bioassay page which doesn't have this bug.

If the Tab2Mage exporter has the same problem, it has to be corrected in 
  it's code as well.
