Slide preview issues
Hi Everyone,
I started using captivate only few days ago and I am already losing my mind for a problem with the preview. I have created, just as a test, a very simple PowerPoint presentation and I have imported it into Adobe Captivate 2019. There are No transitions, No animations, nothing at all but when I try to "play slide" in the preview dropdown menu I get the below issue. Can anyone help me, at least, understand what is the problem?
original slide:

After "play Slide":

just to be clear, the original powerpoint slide is just a plain slide whit the picture you see above as "background" and that's all.
Does anyone know what could possibly be the probem?
Thanks
