You are trying to connect a ShortPoint element to a library that contains a multiple-line column, but when ShortPoint renders your connected data, the result is not displayed on multiple lines, and all content goes on a single line (as in the following image)
Note: To know which ShortPoint elements and fields does support multiple-line rich content, check this article.
The Solution:
If you are facing the issue mentioned above, and you are using a ShortPoint field that supports rendering rich content, then probably your multiple-line column is of type "Plain Text",
You need to create a new multiple-line column that has the type "Enhanced rich text (Rich text with pictures, tables, and hyperlinks)", in order to be able for your information to have the proper formatting as well as to be displayed on multiple lines.
