Presenter content distorted when imported into Storyline

Created a Presenter/PowerPoint file. Imported this into Storyline as part of a project (we have purchased 360). The text, images, and color are distorted when this is imported. 16x9 size is maintained in both Storyline and Presenter.

We have attempted to work with technical support at Articulate but they have told us that our problem is not a "high priority" and will "not be addressed by the development team at this time".

THIS IS A BASIC FUNCTION OF YOUR PRODUCT AND SHOULD BE ADDRESSED. All products should integrate flawlessly.

To those who want to help, here's the issue in depth: https://360.articulate.com/review/content/0723cf6b-94d6-4801-a434-d71d8990ee19/review

I've also included an image to identify the problem.

Further details of the problem (step by step):

Step One: This is an example of me creating something quickly in Articulate Presenter/PowerPoint (as the image on the right of the screen shows). I applied the "Vibrance" Theme to this project.

Step Two: Then, I created a new Storyline project. Applied the "Vibrance" Theme and then imported the Presenter file that I had just created.

Results: Upon import, the font, color of the font, images/shapes, have been lost from the Presenter file. They are not the same at all. The shapes behind the text became distorted in Storyline (as the screenshot shows; image on the left of the screen).

This example shows that there is something either wrong with import, wrong with Articulate, or something else.
