Corrupted my footer / widgets area

Hello, I installed your plugin (Divi theme), took the widgets I wanted and deleted your plugin. It’s left my widget area damaged now and I have no idea how to fix it. The bottom bar is also corrupted.

The site has not launched but I am happy to share the login details with you so you can take a look.

Basically there are 4 widget columns but instead there is one in the 1st quarter column and the other 3 are under it. The bottom bar is not 100%. Thanks
