I've created a very functional template that has 37 modules and though most of the tests work fine for some reason while editing/creating new emails using the template, sometimes content gets duplicated and the editable sections become un-editable unless I delete them from the "Edit Code" window which then results in even weirder results. I've had this issue of content duplication on other templates before but very occasionally, is there a reason why this could happen? is it because there are a lot of modules on the template that the JS on the email editor gets corrupted? This is very annoying and it's very important for us to get this template running without any errors.
For reference, the email is this one:
