Plugin Problem

Hello! I use your plugin and have been disappointed several times already. Firstly, after your updates, the mobile menu on my site stops working. It simply does not open. More precisely, but there is nothing there. This problem was 2 times and now appeared the third time. Now a new problem has appeared, the plugin has started to create a lot of empty space at the end of each page of the site in front of the footer. I thought that the problem was with the theme of the site, but the developer from Automattic sent a video with a solution to this problem. I had to turn off the plug-in for now, since I cannot interfere with the code and fix it. Please solve my problems and most likely other users too. Video below and screenshot
