Eclipse with ADT 21.1 incorrect layout view in editor

So, I recently updated to ADT 21.1

through Android SDK Manager

from eclipse

, then I went ahead and updated eclipse.

Everything worked fine, my projects loaded as expected. So far so good though, but then I went into my project's layouts to do some tweaks and realized that some layouts were not displaying correctly in the editor.

To be precise, I had a layout with an element that is aligned to the parent's bottom and has a bottom margin that works fine on any of my phones, however the editor just ignores the bottom margin and puts the element to the bottom right.

Here is the layout I'm talking about

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/background" >
    <!-- titlebar -->
    <TextView
        android:id="@+id/m_oTitlebar"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:background="@drawable/gradient_title"
        android:gravity="center_horizontal|center_vertical"
        android:paddingBottom="@dimen/contact_button_padding_vertical"
        android:paddingTop="@dimen/contact_button_padding_vertical"
        android:text="@string/contact"
        android:textColor="@color/white"
        android:textSize="@dimen/font_size_24"
        android:textStyle="bold" />
    <!-- logo and title -->
    <ImageView
        android:id="@+id/m_oLogo"
        android:layout_width="@dimen/contact_logo_dimension"

        android:layout_marginLeft="@dimen/contact_logo_margin_left"

I also found another layout of mine which seems to have the same problem
