Oh no! we are sorry to hear this is happening. Firstly, here are a few things you can try to solve the issue.
1. Clear your cache and cookies (not sure how to? Find out how here)
2. Try removing the widget by selecting the '-' button and then re-connect it from the widget library.
3. Read the widget information by selecting the 'i' button on the widget which will help you understand what the widget is supposed to be displaying
