Listing description rendering issues

Got a weird issue, that I’m not sure if you guys can help with, but not sure where else to reach out for help. On our site which is using the Buildium plugin, the description text for listings is rendering all in the same line, example: https://wisconsinprope.wpenginepowered.com/available-units/?lid=239612 .

Compared to their old implementation, which from an HTML perspective is exactly the same, but for some reason it renders fine, see https://wisconsinpropertymanagers.managebuilding.com/Resident/public/rentals/239612 for example.

Is this something with the plugin? Or an issue anyone else has ran into?
