corel to svg - problem while exporting to svg

2. 1) This is how the corel file looks. I've one bitmap background image to the left, one to the right which has a transparent part in the center to display the powerclip and a image inside the powerclip. Here the powerclip is set the order of "To back of the page" so that the border flowers in the background image comes to front.
3. 
20. 2) once the corel is exported as an svg, these are the following images getting created.
21. img1:this is the image inside the powerclip, which is correct.
    
41. img2:this is the background image which has a transparent part in the center to display the powerclip. This should be created without the powerclip image. So, this is not correct. This image should be created without the powerclip image. I'm replacing the powerclip image from my dot net application using javascript. As the background image itself is created as a single image with hpowerclip image , if i replace the powerclip image, i cannot see the image getting changed as the same image is there in the background image also.
    
62. img3: this is the left background image. which is correct.
