Email templates not aligned how to fix that? learning plan notification for learner

[HeenaG]

In Launch Content editor I added some content & image while I added & saved the data and I did not do any changes in Loops, but when I send the preview all the main content is reflecting behind that. 

Added content only in the top but not anything I am adding its going at the back & not showing anything on that & it added extra spaces automatically, how can we fix it so that the content added should reflect on top.
