Frontend Editor not working correctly

Hi. I’m using a theme called Uncode. It comes with a Frontend Editor. It has been working perfetly but when I tried to make an update today I noticed that the Frontend Editor button was missing, along with a few other editing buttons. There is still the option to edit in frontend Editor when I hover over the post and I get the other options to clone, edit, trash etc. When I use this option and make any changes to the page it loses the styling and is not working as it normally would. I also found it hard to change the feature image. I’m assuming I have updated a plugin or setting to create this issue, but have no clue how to overcome it?
