Object placement issue and audio showing style in epub3 file creation in ibooks author 2.3

* I am using mac mini with processor 2.3 GHz Intel Core i7 memory 4gb ,storage 1 tb.

* mac os yosemite 10.10.4 and ios 8.4 and ibooks author 2.3 ,ibooks 2.0.

* while creating the epub file in ibooks author 2.3 the object placement is done in anchored and if I want to move that object at any side that is not moving any other side it is adding in certain place and it is not moving at any side and if i insert any audio media file it is showing in scrolling bar only if i tried to change that style it is not changing any other style.
