Undo is broken: Hit undo a few times and it destroyed my page. I was not able to save the previous work. Lost it all. This is a glitch of the SP Page Builder software. I had 3 changes made to an about us page, when I undid 4 times and saved, it went and replicated the home page. It did not stop undoing as it should work. It just replicated my home page. I can understand I undid 1 more time than the changes I wanted but it is no reason for the component to destroy the page completely and create a home page instead.

Navigation addon is busted: When I added this navigation module it broke my page. It removed all of the backgrounds and some CSS. I am still trying to figure out what else it broke on my page. It happened after I added "sticky" option to the navigation addon. Horrible addon.

Google Maps Addon breaks page: Had 3 column section, added the Google Maps (default) on the right side column and it looked fine. When I switched maps to a different style it merged all my sections together and page was broken. Had to restart building the page.

**EDIT - NEW GLITCH/ERROR *** After adding the Navigation addon which broke my page and removed all the background colors on the sections I am not able to enter any image, gradient, color or video on existing sections. To work around this, I had to create a new section and then configure it again all over and then it will let me add the background color or whatever I want. But on the existing sections after adding and removing the navigation addon, it will not let me change it.
