I've seen another solution with a similar issue but it didn't solve it for me. I renamed Products to Policies. I decided to make a custom module so I reverted the name back to Products and tried to create a custom module name Policies. It continues to say that it already exists. I've went through all the modules and I couldn't find any subforms with the same name. A workaround would be to name it something similar, but I would rather not if it is possible. I also downloaded the translations text file to confirm that there was not anything with the Policies name.
