I tried to clone a module from a custom theme. After that, I renamed the new module and tried to add it to some page. Unfortunately, in the hubspot page modification area, the new module has the same name as the old one and this therefore creates duplicates.
The name which you want to show on you content editor is given in module’s LABEL field. If you leave label field empty then by default pick it will the module name.
